Iphone 12 mini wont charge wirelessly after latest update ios 14.6.

My phone is only a few months old and used to charge fine. However since I put the latest update on the phone wont charge wirelessly. I've tried different MagSafe chargers. Worked fine before. Now when I put it on the Mag Safe charger the green circle shows and the lightening bolt as though its charging but it doesn't charge at all. What can I do?
