A similar set of screenshot for Avast Secure Browser; I think subtly different to some of the previous guides.
Top Right, Customise & Control White arrow in Red dot
“Settings” from the right hand drop down, not “Security and Privacy Centre”
Left Hand side “Privacy & Security” (yes confusing isn’t it)
From the middle “Site Settings” NOT “Privacy Cleaner – clear browsing data”
“View Permissions & Data Stored Across Sites”
Navigate down to this site’s data N.B. Do Not Clear All Data via the green text in the box
Use either the three dots, or the right arrow to Clear Data and/or Reset Permissions, but double check the bit I’ve highlighted Yellow, to make sure you only change this site’s data.
Double check the confirmation box, hopefully job done.
