Dual Apps does not work. Everytime I enabled it, most of the apps will force quit.
Device: Redmi K30 Pro Zoom Edition (China)
I'm on xiaomi.eu_multi_HMK30Pro_V12.1.2.0.RJKCNXM_v12-11
This is an official Android 11 issue that seems to have been fixed on Beta/Weekly. Don't use Dual Apps on Stable, or move to Weekly, that's all I can advise.
