Howdy.
I would like to suggest to add a help FAQ in the iOS App -> Settings -> Support -> WordPress Help Center -> Cannot Login section.
For logging into self-hosted sites that use the popular Google Authenticator Plugin, I believe it is a good idea to suggest users to hit Update Profile button before they can use the created App password in the plugin. I also suggested this to the plugin author here. However I thought it may also be good to help users that bother to check the Help on the app.
I am more than happy to help implement my suggestion. ( Although I have no clue how to do this at this point in time). Please let me know. Thank you.
Regards
Chaitanya
