Recently I got a new phone and the option of watching videos to avoid waiting to battle appeared to me I think for the very first time (and it worked!). I have never had this option so I didn't really know how it worked and if there's a max number of videos you can watch, etc. The first day I tried it I used it 8 times in a row. Then the button disappeared, so I thought that maybe there was a limit per day. Next day it appeared again and I could only use it 3 times before it disappeared. A few days have passed and the button hasn't appeared again. Is there any problem with it, or does it have a limit that I don't know about? (I have the latest version and everything is updated).

Thanks in advance!
