Ok, I deleted & reinstalled both apps just now. Signed out & signed back into both. Also tried a new export of just 1 single traditional cache. All no go. Same error.
Oh well. Don't worry about it. Its working the other way, and I've lived it for over a year, so not end of the world.
I love Cachly. I've tried all the apps over the years, and your rocks. I go back to the stone age before paperless was even a thought. Printouts. Then Cachemate on an old Sony palm pilot. I test lots of apps but I keep coming back. Cachly has come the furthest the fastest & keeps improving with things I never even knew I wanted. Thanks for trying with my stupid bug issue.
