Won’t open file

[H36978042jhvf]

 I made a PowerPoint file, opened it in adobe mobile app. Sent it to someone. Says this message. Opened it from the same device on a new email and it still says this. I don't understand how I wouldn't be able to view it on the same device I made it on from another account. Doesn't make sense. Pls help urgent!!!
