"Problem downloading attachment, please check your media storage"

[Alma Calderon]

Hey guys!
This is my first time posting but I've actually been around for a while. I recently ran into a problem with one of my apps though and I can't seem to find a fix for it anywhere. it might be something super simple, but I can't fix it . Anyway, I use the blackboard app in my note pro to download pdfs and anotate them and it's actually super useful, but just today I tried doing so during class and I got the message:
"Problem downloading attachment, please check your media storage."

I turned my tablet on and off. I Uninstaller the app and I tried a few other things in twrp like wiping cache and such, but nothing anyone have any idea how to fix this? Thanks!

It means "please check that you have enough free internal space to download this file".

You fix it by deleting stuff you don't need. (Or stuff that you don't need on the phone all the time, and have backed up to a computer and a cloud account or two [which your whole phone should be already].)

I have about 8gb of free storage though? And the pdf is not very big? I already wiped some of my files to see if it helped but didn't fix anything?

The only other thing I can think of is that the error message is wrong, and the file isn't a valid pdf file.

Hmm, alright I'll keep looking into it. But that's not the case I can't even download old pdfs I had downloaded before the problem started. Thanks anyway!
