miui kills autosync + no single sim message sound?


Jun 11, 2019
i am using stable for two weeks and hove noticed, that miui kills autosync. i need all mail notifications at once, because my work orders come by email(i am using push notifications). i am using bluemail app. it is in autostart, all permissions, no battery saver. stack mail app does not work at all. my email is using client certificate and when i try to configure stock mail app i get error "mail keeps stop working". how can i prevent autosync kill?

i have found that there is no way to choose message sound too. in global rom(beta at least) was a function to choose single sim message sound(like it is with single sim call sound). or did i not found how to do this in this rom?
