Judging by a few reviews I read in playstore, they serve up quite a fw ads. Could be that, and or other issues affecting the stream. But, I saw lots of other issues in the reviews as well. It's possible that it is a streaming issue from the source, like using an "anti-Adblock" in their software. Thanks for responding, but, I'm not going to install this app, because of permissions. The ad SDKs included gain the same access as any app. So, I am real picky about what I install. Sorry I can't help, but perhaps gsava, the owner here, will respond when he has time. Generally, he is very busy.
You have to remember: nothing has been or will ever be 100% accurate. Personally, I think the developer(s) have done an amazing job making this. It also blocks about 70% of the video ads in the official YouTube app.
I have been using this app for some time, but won't have Nougat until sometime next month I think. The first thing I would do, is go through all settings to see if something was moved back to default by the update. Especially Google settings. But permissions would be the next thing to look at too. Also, it could be something specific to the device OEM you are using.
Could you check thing out, and maybe let us know more about your device, software version and patch level? I just got an update to November 1st patch level back on the 12 th of December, and it broke several of my apps on Sprint HTC m9. Coincidentally, data monitoring apps, to be more specific. But, I'm using Block this as I type, and it's working just fine. I would be interested to know what steps you have taken to try and resolve the issue. Any information would be appreciated. Thanks.
