- Option to revoke messages, when selected both non-revocable and revocable messages at the same time
- Revoke messages disabled by default, when all of selected messages are incoming
- 2FA email verification by code
- Improved notifications displaying: notification internal content update will no longer trigger notification rebuild. (this resulted in many device-specific issues, e.g. on Samsung devices notification pop-up disappeared too fast, notification displayed twice on Edge Screen, etc)
- Improved some error messages

- Log out, log in again with different account, data from the old account is shown in the app drawer.
- Some other issues on 2FA setup
