Recurring notification to upgrade to subscription ACP?

So I checked the notification thing for Acronis on my toolbar, and above my last successful backup report, I saw a notice that Cyber Protect Home is available. I looked it over, decided that I don't want to be dragged away from my perpetual license that I paid good money for and forced to pay every year or lose my ability to do local image backups on my computer.

I dismissed the notification.

The next time I booted up my PC, the notification was back. I dismissed it.

The next time I booted up my PC, the notification was back. I dismissed it.

The next time I booted up my PC, the notification was back. I dismissed it.

The next time I booted up my PC, the notification was back. You may have noticed a pattern.

How do I properly dismiss this notification, which is continuing to try to sell me something I don't want?
