Have a look at the following thread my friend...
Heads Up PC Players
Some goods reports... others not so much
Already read that thread, didn't really help.
Experienced the same and finally decided to reset ID and it works. On android.
How do you reset ID?
Some more info...
I use android emulators on my laptop to watch the videos - 2 instances of Nox, 1 instance of Bluestacks, 1 instance of LDPlayer, and 2 instances of Nox on another laptop... all running concurrently. Running this many instances, and sometimes even two more if I also do it on my tablet and phone, has never been a problem previously. Having not worked for 2 or 3 days, this morning I just opened up a single instance to see if it worked, and I got a video. Thinking it was now working again, I opened up the other instances and immediately got "no videos" on all the subsequent instances, and then I got the same on the one that was working right after the video finished. Closing them down and restarting them made no difference, nothing worked any more, so I left it. Then this evening, after the 'new videos' day started, I opened up a single instance and once again I got a video. I let it play out, clicked 'more videos', and got another. Thinking it was now working as it should, I opened up the other instances of the emulators, but once again I got the "no videos" message. And just as happened this morning, the one that was working also now gave the same message.
So I'm wondering if they (whoever 'they' is) have somehow disabled the use of more than one device running videos concurrently?
