ARP_ASUSYes it's .99 and all the required permissions are given for both apps(twins) only not getting notifications on top of screen when I receive any group or chat message in whatsapp main app, twin is working fine. Did a reinstall also no help
Can you confirm, if your software version is .99.
Check under Settings => System => About => Software information.
Also, kindly go into settings of WhatsApp and General setting check if all permissions are given and Notification is active.
