Ha ha, I’m running Sailfish (again) on another XA2 at the moment; just to see if much has changed since I was last there about 9 months ago.
Since your device was on android 9 might be worth considering installing the eOS pie test build. This would give you a better experience of what to expect under eOS going forward. I ran this build on my XA2 from August to December 2020 without any real issues.
