There are 2 things that stop me from being able to watch videos on my old android phone.
1. If my connection is slow, the "Next" video times out and I get the "try later" dialog. In this instance, I exit by pressing the the "clear" button on my phone, I clear the phone's cache with this button. It is on the bottom right on both of my phones. I then re-launch WGT game and try to watch the next video.
2. If the above doesn't work, you'll get a small dialog saying, "there are no more videos" In this instance, I clear as above, then reset my AD ID number. To do that, on my phone, I click settings, then scroll down to Accounts "Google", click that, then find an entry called "Ads". Click Ads and, near the top is a setting that says "Reset Advertising ID" Click that and click "OK" in the resulting dialog. Close settings and re-launch WGT golf and try to watch videos from there.
Hope this helps,
