Push notifications, problem

[rocpac]

I have always permanent WhatsApp in "not optimize battery", and I can't change it. Also If I want to change this setting to another app in "Not Optimize battery", It's revert again in the next minutes to "Optimized". Pls I need to fix this to have push notifications in a mail app .

I have the last beta MIUI 10.4 9.5.9
