Not getting extra coins after watching videos

I have strategically waited to sign in at certain times to maximize double up from the coins I earned while gone. I watch the videos as instructed.
Every time Im over around $80K earned while gone the app makes me watch the entire video and then freezes at the end. Im forced to shut down the app and when I come back into it I have not received the extra coins.
Anyone else have this happening to them?

I don't watch the videos to get more coins but I do watch them save 2 hours in cooking recipes. I just watched two ads to do this and had no problems.
