After years of refusing to do it; the lack of support for iPassword6 in iOS13 and Catalina, I upgraded to iPassword7 for the family. BUT I can't use it on iOS13 at all, it crashes trying to put in an account. I removed the old apps; downloaded the latest from the store, run it. Under "Already using 1Password" I touch "1password.com" and it crashes.
EDIT : I'm running on a iPhone6sPlus if that matter.
1Password Version: 7
Extension Version: Not Provided
OS Version: iOS13
