Hi, if you are on the latest version, 3.0, then open the app, tap the menu top left, see whitelist, tap that, then the plus button bottom right to load a list of your apps. Then select which ones to add to whitelist. That's it.
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.
Also I would add Incase anyone else has this issue, that HTC added a new app to nougat update called "Boost+" and it can regulate apps in foreground and background. Open the app, then background, find the apps you want to be left alone, tap the app, then the third choice is "off". I'm not entirely sure if this is in addition to battery optimization, but whitelist the app there also.
I updated to nougat on HTC m9, Sprint a few weeks back, and I've not experienced anything like what you mentioned. I would reinstall BT and try again. Do you have any web filtering by an anti-virus app? What browsers did you experience this issue? I have 4 different browsers, Chrome, Firefox, Adblock Plus, and Brave. Non have had problems with browsing while on BT. One thing I did have to do after updating was to reset all app permissions, or actually I reset all app preferences and RE-enabled the permissions for each app. But largely I was having a battery drain problem, since fixed. I also re did my backups from "back up & reset" and automatic restore, just to make sure everything was fresh. Basically, I turn off then back on, which cleared the old out, and stored all new backup data.
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.
