Yes, I notice the same things with the Xperia 10 II too.
In addition to the installation with Aurora, I would add that WhatsApp, after displaying a newly arrived message, closes once you leave the chat. However, it appears to continue running in the background.
I add NexiPay and WPS Office don’t work at all: they seem to start but then crash.
Ah I tried with a full flash, installing microG, then I did a full flash again and didn’t install microG, but the result was the same.
