I'm using the current version of adguard and have a lifetime subscription. I've been frustrated the last couple of days with my Samsung Galaxy S7 Calendar not syncing properly. I'd add events to either google calendar via the web or an exchange calendar via outlook (that I have set up on the phone using a native exchange account) and events would never appear on the phone. When I went into the phone accounts, it should no recent sync activity for either google calendar or the exchange account. Today, I disabled adguard while testing a different ad blocker. I forgot re-enable it after and I just realized that my calendars are syncing properly again. I'm not 100% sure it's the culprit and I need to do a little more testing, but, initially, it sure seems that's what's going on. The timing certainly is right as well as it does seem that I've had calendar issue since about the time I installed adguard. Is is possible that adguard is the culprit here. Are there any settings that I could use that might stop adguard from blocking my calendar sync?
