Another annoying thing: very few apps are copied from old device to new devices and bring their settings and most importantly login. Of about 80 apps on my device, only five or so are ready to use after a migration.

Going through dozens of apps, doing logins, 2FAcand changing settings is a PITA.

Devs do a poor job on that front.

Developers basically need to opt out not to use that feature. 2FA apps do that for understandable reasons (including on iOS).

In my experience just about everything but WhatsApp and maybe Signal work out of the box for apps downloaded through GPlay.
