When sending SMS I cannot change send number (DualSIM phone). I set SIM1 as default SMS sending SIM. Enter app. Touch SIM choose icon, changing to SIM2 and after few sec app reverting this setting to SIM1. When I set SIM2 as default SMS sending SIM and enter app, change send SIM to SIM1 it keeps reverting back to SIM2. Cannot send SMS through Microsoft "Your phone" in Windows 10/Windows 11. Constantly get "Sending failed, touch to repeat". But only when I choose SIM2 to send. With SIM1 works fine. Same in Google Messages Web.
