Hmmm i have the same issue, newest version built with my Packer.
I live on Poland, i see ads before a video
My location is Poland and i have unskippable ads
It works on non-rooted devices, I don't know
It isn't packing with microg, I will fix everything and remove the GUI in the next update
you have to add "microg-support" in the "add integrations" section
sorry for claiming it's added automatically: 
you must add microg-support
i'm creating a tutorial
