SHM Gone Crazy/Uncontrollable with Classic

Good morning! So several days ago my SHM randomly armed in the middle of the day and alarmed. Not a huge deal, but at the same time my Classic App has stopped working. It just keeps telling me network error no matter what network I am on. Now ever hour, on the hour, I get a text that there was an intrusion detected and I cannot figure out how to get it to stop. Hopefully I am missing something easy in the last 139 hours! Thank you!
