Passwords rejected opening databases on new iPad 18.1.1

[Charlweed]

I'm trying to setup Kypass 6.2 on a new iPad, but the app keeps saying that my password is wrong. The app will not enable the "show password" Eye icon, and will not allow me to paste the password from the clipboard. I have no trouble opening the same database on my old iPad pro, running iPadOS 17, or on my iPhone with 17.5.1.

On the new IPad, I tried creating a dummy database with the same password, and I cannot open that either. I then created another dummy database, gave it the password "1234" and I COULD open that database. I'm afraid that there is something about my password that Kypass on my new iPad rejects. I have also verified that I can open databases locked with a keyfile.

The password has numbers, upper+lower case, and simple punctuation. This would all be much less mysterious if the "show password" Eye worked, or if paste into the password field worked. The fact that they don't seem to be bugs.
