I just got my S25 Ultra but wireless charging and reverse wireless charging are not working with and without cover.

For wireless charging I have enabled the fast wireless charging option but still it won't charge.

For reverse wireless charging, when I turn on wireless power sharing it turns off immediately with a notification saying " The device you are trying to charge might not support wireless power sharing or it might not be able to charge now.

What device are you trying to charge? It is not possible to charge the Watch Ultra nor GW 7 in this way.

For me to charge any device using this, I have to turn this feature on but when I turn it ON it turns off automatically and the same notification appears that I have attached above.

Do you have metal objects. It will fail at times when not lined up properly. Also to strong of magnets may mess with it.
When I use my rocfom case certain device won't charge due to magnetic interference
