Hello I have an Ipad air 5 M1 (2022). For Over a year now I have been using it. But recently i am seeing when i am done with my classwork, i attatch it to the side of the ipad where it charges. it pops up and shows charging. After 2-3 hours i come back and check the pen is not charging but discharging as well. Its a issue going on for few days now. I am now currently updating the software.. IDk if it'll work or not. Any solution of this?
