Device not showing up on Devices list

The title says it all. My Samsung Galaxy S4 isn’t showing up when I log onto my account on my.avast.com and go to Devices. It’s not there at all. Before, it said it was ‘archived’ and I had to delete it, now I go to my phone, go to anti theft, disconnect my account from avast, and re connect it, and i get an email that says my phone number changed ( which it didn’t ), and i go to the device list on the account, and I don’t see the device at all! Please help me!
Thank you so much for taking the time to read this. I’de really appreciate it for a quick fix. I love this program.
