1Password 7 won’t open with IOS 16-Need to back up data to retrieve in 1pass. 8!!!

Hi Dave,
The app (vs 7) basically acts like it will open for 2 seconds then doesn’t open at all so only thing to take pic of is the app icon. Problem is actually on my husband’s iphone which is a little diff model than i have. I’ve not updated my 13Pro yet and 7 is still working, but it doesn’t show his vault data. The main glitch is that for some reason the entire time he used the 1 password app and entered info, it wasn’t syncing to our account, otherwise it would have just repopulated in vs8. I will look again more specifically tomorrow at phone version etc and post what I find. Surely there’s a way to get back in it😩
Thanks so much Dave!
