Constant upgrade prompts on free version?

I have been using the Avast Free for some time and recommend it to everyone. I am used to it prompting to upgrade every year or 365 days and I can say Stay with free and it stops.

However, recently I installed it on 2 new systems, and instead of 365 days, it simply constantly prompts to upgrade. I say stay with free and it just keeps prompting. At least once a day.

I just want to stay with Free. Is that no longer possible?

Try Avast>Menu>Settings>General>Notifications
Set “pop-up notifications treatment” to “Limited Mode”
See if that helps.
