iPad photo and videos missing fix

I use an iPad Pro and recently used airdrop to send 40 videos to my iPad from my iPhone.

Once the airdrop was complete I checked the photos app and there were no videos in it

I checked the storage usage in the settings and it showed there were videos in the photos app.

So I tried all kinds of tips mentioned online.

The one that worked for me was to reset all the settings in the settings app. Not content reset

The iPad restarted and I had to give the wifi and iCloud passwords and after restarting the photo app correctly showed all the videos. 

I think it's some kind bug in photos app, when you send a lot of photos or videos through a computer or airdrop, hopefully they will fix it soon.
