Back to ads again on a paid subscription-Android S6 Active phone

Okay Avast, I’m getting sick and tired of this. This is the 3rd time this exact thing has happened. With this mornings upgrade of Avast Mobile Security on my Samsung SM-G890A (s6 active) I have gone from paid subscription to free version with ad’s. Thank you very much. Last time this happened it took over a week for you to correct. The time before that not as long. Please advise me on how you or I can correct this. Thank you. James

Sending you a PM.
