first time I used my fp5, i was shocked by the amount of google apps installed. I immediately turned it off and change for a degoogled ROM .

Until you can use /e/OS, If you do not use a VPN, I can recommand you to use blokada to limit the trackers and ads. Blokada 5 is free, blokada 4 is free and allows you to choose a custom DNS.

I didn’t know about lichess. There is an application on android, both on play store and f-droid. This app is amazing !

Thanks for the discovery !
