My son and I both have s20 FE 5G's, and both are suddenly experiencing fast charging issues. It may be related to updating to the Android 11 update. 
My phone suddenly stopped working with my non-oem wireless stand. It will charge, but not fast. I tested it on my friends Belkin wireless fast charger and it worked fine. I tested various combinations of his and mine plug, cable, stand and determine that if my OEM Samsung 2.0amp fast charging plug or non-oem stand were in the path, it would not fast charge. I've tried my sons OEM plug and cable with no success. But I have another OEM plug and non-oem cable that fast charges fine (not wireless).
Now my son is using his OEM Samsung plug and cable that came with the s20 (not wireless). Sometimes he'll plug it in and it fast charges, sometimes it won't fast charge, sometimes it says it's fast charging but doesn't, and sometimes it charges super-slow. We've tried multiple chargers and cables with the same result. He just had to keep plugging it into his phone until it starts fast charging.
Have we been affected by a firmware issue?

I have the same issue after the latest update on my S20 Ultra 5G.  After the update, Fast Wireless Charging will not work with any of my fast chargers, but they worked before the update. Fast Wireless charging is turned on, so it's not that. Samsung needs to address this ASAP.

I'm in the same boat. No fast wireless charging after latest update. My wife is not on the beta program and hers fast charges just fine. Same phones

This stinks.  I have S20 5G on T-mobile.  Got update March 22.  Fast charging on my Ubiolabs charger that worked for past 1.5 yrs Costco stopped working.  It works with no problems on my son's S10+
