I’m trying to install 1PW on an older iPad mini. I scanned the account QR code visible on my phone, which auto filled 3 of the 4 fields on the iPad. I entered my master pw. When I hit enter, it says, “check your email and secret key,” and does not log me in. My email is correct. Since Face ID is so bad, I enter my master PW several times a week on my iPhone. So I definitely know what my master PW is. I’m not sure what’s up. I also verified that the auto-filled secret key is correct.
If it helps, my iPad mini is running version 10.0.2, and is model ME276LL/A.
