troubles uploading database from desktop to Samsung Galaxy A31


Having updated to CT 3.517, I have installed the new client to my Samsung Galaxy A31 with Android 11 via Play Store. When I try to transfer the application via USB, the dialogues appear like normal on the desktop, but the new Android App can not find the database. It worked with the Simplesample, but not with the Biodiversity with “Plant Identification Filter (CTX)”, which I tried as well.
I could not locate anything in the file system.
many thanks for help with troubleshooting.

Cheers, Alex

Did you try to save as CTX to MDB before?
