Unsure why you seem to be having so much problems running these videos. Just before posting this I ran all videos(75) running both nox and bluestacks on a windows 10 computer, a samsung a7 tablet(8 inch) and a amazon fire tablet(10 inch) all at the same time.
The only thing that I noticed is right at first both tablets would popup that I had no more videos available, but I knew there should be some there and both on the computer were running videos. By selecting the video button again they both started running videos. I have be seeing this lately on tablets. BTW the computer is hard wired to my internet, the tablets are running on my wifi from my router. I run cable modem, router w/wifi, computer. I do not run behind a VPN. I have noticed and posted before on other topics that it is a crapshoot if wifi will work consisently.
I have 2 computers in this room and at times I have run both computers and both tablets all at the same time. Most of the time all works great. But I have seen at times, tablets working off of the wifi won't work, but the hard wired works fine. My internet wired runs 300+, wifi runs around 200+, I have even gotten down to just the tablets and they haven't run.
Know where you need to be credit wise after running the 150 and also know when your cut off time for the day is, mine is around 2 pm. So If I run vids after 2pm, I won't be able to get any more until after 2pm the following day. So at times I have to skip a day as I normally run mine in the morning, I am on east coast USA, so I should be 5 hours behind you according to your flag.
