@johnymacclen Thanks for the quick reply. Here is some more information.
Yes, Opera is the only/default autofill device. It is the default browser, and no other service is trying to fill the password entry I do not think PasswdSafe blocks it. I typed the password in Notes, copied it there, and pasted it successfully into PasswdSafe. I have tried tapping the field and long-pressing but to no avail. The phone is an Oppo Reno 11F, running Android 16.0.5. I do not understand how I can make Opera fill passwords in Notes. When entering passwords or PINs in another app, Opera offers to save it. It does not do that for Notes.H
