When it was 20 GMT (3 pm my time) I started the checking the store every few minutes. I uninstalled RR3 from all my devices and at about 3:40, I started installing v 10.4.
I ran the Formula E event. It had some annoying moments. But I was able to finish it and run some of the motorsports career.
This morning, I ran ads on my Android 12 device. No delays but all the ads were the multipage nightmares for stupid games that frequently opened the google play store or the galaxy store. I spent a lot of time closing the stores.
It took three hours to do all the ads. Good job for no delay, bleah for these horrible ads. I might try ads with Android 10 to see if v10.4 ruined those too.
