Proton is great, but WOW did they royally screw up a most recent Android app update. Dark mode now makes text black on dark gray. Biometric locks were turned off without user action. Sent messages and received messages with no font set show up in fixed-width font. Backspacing to the end of one word automatically deletes the space between that word and the word behind it. And if you're the last one to reply in a thread and want to add something, it leaves the "To:" box empty because it can't figure out you don't want to reply to yourself--and doesn't show you any of the addresses for past messages in a way you can copy and paste to fix it. Oh, and they added a THIRD tap to archive an open message, as though two wasn't already too many for the number one thing users want to do once a message is open.

I haven't seen an app update break basic functionality so completely in about a decade. It's atrocious.
