So I’m going nuts trying to find a stand up wireless charger that works. I don’t want to keep buying them and then returning so many to amazon. I have the s21 ultra with a skin and a thin tpu clear case. It’s weird bc I didn’t have this issue with my not 20 ultra and I had a thicker case on that one. But it’ll charge and keep turning off an on, or will switch from fast charging to regular charging or just stop all together.
