No notification on FlymeOs 6 for Newton application

I have installed Flymeos 6.
The problem is with Newton email app, that doesn’t work with notifications.
Other apps like messenger and WhatsApp are working fine.

At security app I have activated all permissions.
Any other ideas?

make it a system app with link2sd.when I got problem like this that was the solution

In order to do that I need proper rooting, which doesn’t work for Flymeos 6.

root is working fine for me!!
