It's not a OneUI 5.0 beta-specific behavior, it's there since OneUI4 (and if I recall correctly even earlier). Basically, if you're using an eSIM SIM card manager appears every time the phone is rebooted, asking you if it's okay to temporarily disable eSIM to scan for physical SIMs (even if you don't have one, like in my case). Every single time we have to press "OK" while you could just add a "don't ask anymore" checkbox. Please consider checking this out, thanks devs!
