I had a moto g7 power that would flawlessly cast anything to my Roku tv and using the Roku app would function as a remote as well.
Got a moto g 5g - it only works 5% of the time now, not even finding my Roku TV but it will find all my other Roku boxes.
Also went from s8 which worked 90% of the time to s20 Fe which now works 5% of the time as well.
Total **bleep**.
