For the last several weeks, I have been having an issue with my apps not recognizing my wifi connection. For instance, Google Photos, which I have set to upload photos whenever I connect to wifi, was never uploading photos. In order to force the upload, I would need to change the settings to allow uploads over cellular data. I would do this when connect to wifi, and then the photos would upload, but I could never be sure whether my phone was using mobile data or not. Similarly, I have Pocket Casts set to download new podcasts when I connect to wifi. I have had to manually download new podcasts before walking out the door. Even when connected to wifi, I would get a warning that I was not connected to wifi when forcing a download. I was on the developer previews of Oreo when the issue started, so I had assumed it was an Oreo problem. But I've now been on stable 8.1 for a couple of weeks, and the issue is still not resolved. Today, I booted into safe mode, and my photos immediately uploaded. I then rebooted and disabled AdGuard, and all of my podcasts began downloading. So it appears this is being caused by AdGuard. Is this a known issue? If so, is there a solution? Maybe some settings that need to be tweaked. I tried a quick search and didn't see anything, but I imagine I'm not alone. I appreciate any thoughts or suggestions.
