Avast Antivirus not running scheduled scans?

[ryujin_matt]

Several weeks ago I went into "custom scans" in Avast and created a weekly full virus scan and set it to run weekly on Saturdays at 9:00 am. I did the same thing to schedule quick scans several times per week. But when I go into "Scan History" now, it shows that only 1 quick scan has been run in the last 3 weeks. It hasn't run a full virus scan at all.

Why is Avast not running the scans I've set up?

Program version: 20.5.2415 (build 20.5.5410.561)
UI version: 1.0.532
OS: Windows 10 Pro, version 1909, OS build 18363.900

Any help appreciated!
