baljit1221 no problem, just wait for the next release. You will soon get an update. We have fixed the issues.
Note: the issue is only with Chinese OEMs like older models of Xiaomi, Oppo, Vivo etc. Other brands like OnePlus, Samsung etc has no issues.
These Chinese OEMs has issues because to provide a better battery life they immediately close all the apps that are running in the background. We had to do alot of things to overcome this.
