The dual messenger bubbles are not working anymore after the yesterday update to Android 11 and One UI 3.0. The option is not saving the settings in Settings > Apps > Messenger (Dual) > notification and then the first option is "Show as Bubbles" it showing none, when i tap on it and check "All" and go back it still showing "None". This is bug only for Dual messenger but on normal messenger it is working fine and saving the settings.
Please solve the issue.
But it was working fine for also dual messenger. Now its not working for whatsapp normal or dual. And same for fb messenger for dual but on normal messenger its working but its changed and using now UI 3.0 bubbles instead of fb chat heads.
