I use the Dual WhatsApp feature on my S9 and for years pictures and other media have been downloading into my gallery. However, a few months ago installed a SD card and backed up pictures and videos. Since then one of my WhatsApp account stopped downloading into my gallery, despite having the media auto-downloaded settings activated in WhatsApp. Can someone shed some light on what might be causing this problem?
have you tried to uninstall and reinstall? clear cache and data? check all permissions as well.
seems like whatsapp issue.. you might wanna contact whatsapp developers on play store
i tried all the options which you have suggested but none of those are working, i think it's not the problem with the application bcoz the original messenger is working fine, only the problem with dual messenger app
