I'm sure of the following.
It occurs after saving a log, not submitting one.
Once it closes the window and you view the map again what you are wanting to do is to click the next icon in the series. Now here is where the lack of repetition comes in. It is something to do with either the number of icons on screen or the proximity of the icon to the one you opened. Something that is determining what details to show in the pop up.
Whatever it is when it occurs clicking anywhere opens the last cache. Note I do not for a minute think as per original poster that it is copying the cache details. I simply think it has cached the last cache details in a variable and the click is opening the previous cache. 
The fix is to zoom right in so that only the cache you want is visible this seems to be enough to force the variable to be set to the right cache. 
To fix I'd focus on anything that stores the cache clicked, or any proximity thing to make the selection of a cache easier. Specifically anything that would be affected by a zoom limiting what cache it could be when you click on screen. 
 
Hope this helps. Clearly from the user groups comments it's quite a common bug. 

This for sure is something I will take into account. My plan is to not even show clustering after a certain zoom level. Stay tuned for more details and testing.
 

I've had this a lot too ususally happens when phone is in anything less than a 3G area. I'd suggest that if the user is in the offline map or using offline map and not on wifi then it defaults to saving offline. Typically if a user knows they are in a poor signal area they will switch to offline maps and/or offline tab. Cachly could take that as a cue to use offline mode for saving waypoints (and cache notes).

Welcome to Cachly! Do you just mean a feature that zooms the map in the closer you get to the cache? If so, this isn't yet possible in Cachly, but we do have it on our feature list!

I think this is separate from the locking the map in rotation mode Nic. I'd mentioned a while back that one of the features I liked about the Classic app that Cachly doesn't have is the "auto zoom". So that as you move the map zooms so as always to keep the current position and the target on screen.
This is particularly useful when you have phone in a holder on dashboard of car and you are driving to a cache location to park up. At present when you get closer the map doesn't change at all other than the option to rotate. This means that it is at one zoom scale - when driving often this is a few miles out but when you are in the last few hundred yards to parking its REALLY handy for it to show it at a far more detailed scale as at the scale you started out at the dots are basically overlapping, so what you want is to zoom in. Doing this manually means taking your hands off the wheel to fiddle with phone which is inadvisable. On the classic app it would zoom as you moved so that as you got closer it was very easy to see and so safer whilst driving.
Of course it is useful when on a lengthy walk too as you focus in on the area you want to search.

What map provider were you using? Map tiles will be downloading directly from their providers, so I am not sure what the slowdown would be. Have not seen this issue myself.

  Absolutely. In an upcoming version this screen will be completely changed basically making it a one tap download that users won't have to think about. It will also download all zoom levels as we are changing the algorithm to only download tiles in a radius around caches.  
  This feature can be turned on by tapping the current location button to toggle its "modes". There is No Follow, Follow and Follow with Heading. 
  Both these have been requested by other users as well and are something we are working on. Showing that a cache has been found, but not yet submitted the log wouldn't be hard. The DNF feature is something a bit harder since Groundspeak doesn't support this in their API. So we will need to use our own server to handle the DNF's for all users.  
  Great idea about the zooming. Will get this added to our feature list.  
 
Absolutely. Working on some additional ways to show accuracy throughout the app. Should be included in our next release.
 

 
Thanks for using Cachly! I highly value user feedback, so I really appreciate all of your comments and questions. My goal is to make the best Geocaching app out there, and this can't be done without users help!
