How to disable promotional/expiration popups?

I keep getting popups informing my Avast Premier has expired, recommending a reactivation. How do I disable it?
I’ve checked and I can’t find anything helpful

What Avast Premier are you using 60 day trial or Full paid version ?

If you have paid version Avast Premier installed and it has expired, you either need renew your license or you need to uninstall it. During the uninstall process you would be offered to convert to the Avast Free version.

If it’s a 60 day trial you also need to make sure you aren’t going to be charged for the product.
60 day trial requires your credit card and a commitment, unless cancelled, to ;pay for the full version after the trial.

I was using the 60 day trial and i cancelled it but im still seeing pop ups

If you are still using the trial version of Avast Premier (?) you are going to get reminders. You would still have to go through the process of uninstalling the trial version of Avast Premier and convert to the Avast Free version.
