HI VivekJ, Due to improved security policy of Google on Android 11, storage memory is separately managed for each user. As dual messenger works based on multi user service, storage memory of dual messenger don't be shared with other apps. Therefore downloaded images while using dual messenger do not saved in Gallery app. To check downloaded images, please go to My Files > Internal storage > DualApp> DCIM > Messenger app folder
Hi, Sorry for the inconvenience caused to you.
As of now, we don't find any alternative as this is due to the security policy set by Google on Android 11.
