Until yesterday, i could translate messages using action in message popup, and now i can't. Was the feature "rolled-back"?

All in all it's not a bad app but notifications are delayed on my devices and have no content (notifications are just blank except the ones that say "2 new messages in 1 channel") and the app lacks a dark mode which is pretty disappointing because all messaging apps and system apps I use have a dark mode.

It's missing some features like pinning messages in a channel and editing messages. But overall nice thing. Letting you search for members of your organisation and such.
