I think its intended to line up with the iOS and iPadOS naming scheme. They pooped out an update earlier this year to bring all three OS’s up to the same version number as well.

Requiring the use of their own app is only marginally better than not supporting it at all. I try to minimize the number of apps pn my phone, and banking apps are prime examples of a use case that can be completely fulfilled in a browser. Even if I used the app, I would prefer to be prompted for non-biomotric MFA each time I sign in anyway.

For the love of God, someone inform Citibank and Chase of this. My dinky little local credit union allows me to use TOTP, but Citi and Chase still only seem to support SMS.
