Cannot delete video in iOS app

I have transferrred all the video in-app from the ipad to the SD card successfully.

They are not feature films, but 9.5 GB 30-90 sec home video clips imported via the SD card slot.

When I Select All and try to delete I get an error that says “Could not delete some video” and they are all back and completely playable.

I have deleted and reset the ipad twice and removed the SD card from the wifi drive. I delete the Sandisk app and my memory frees up. I re-install the app and everything re-appears…???

I have to clear room off my ipad, and would like to use the wifi drive again, but I’m stuck with a full ipad and an unuseable drive. 

Suggestions? Thanks!

Can’t you plug the media drive into your computer via the USB cable and delete them that way?

To delete video: you open Settings > General > Usage > Manage Storage > Videos. Find the video/movie you want to delete and swipe it to left, and then tap the red “Delete” button.

The best way would be to just delete the app and reinstall as all the settings would be linked to your id and you don’t need the media anyways https://speedtest.vet/ https://vidmate.bid/.
