ipad mini 4 not connecting to Phantom 4 pro v2.0 RC

Good day all, my IPad mini 4 doesn’t want to connect and/or stay connected to my Phantom 4 Pro v2.0 RC. If I coonect it, it shows on the ipad it is charging and then 2 seconds later it is not charging and it doesn’t connect to the drone. What can the issue be? The ipad software is 14.6. I tried it through various flying apps and nothing.

What can the issue be?
