Where to find shared video from airdrop

If you were sending the video by email, yes a 20 minute video would be way too large. How many GBs is it? I do not know if there is a limit on AirDrop but here is a thread discussing the same thing, seems like up to 8 GBs is ok whereas anything over this is iffy. A 20 minute video would be very large indeed. May have to transfer the video to a computer first and than transfer it back to your friend the same way. Good luck.

Airdrop file size limits?

Pavankuman, yes by default Videos appear on the Home page and by default they AirDrop to Photos. However lots of users like myself move those Apps around, mine is now inside the Utilities Folder. You said you could not find the video you sent so I took it that you had looked in the Photos App already. I would try sending it again and looking at Photos.

Is it in your Video App which could be on another page perhaps or even inside a folder like Utilities?

Videos taken by your iPhone are in your Photos app, so sharing one would put it in their Photos app (not the Videos app). Within the Photos app there is a Video category, look in there.
