Potential bug with Fully Kiosk Browser and Color picker / Favorite light colors

For Fully Kiosk Browser users:

there seem to be a bug with FKB and I want to double check if some of you have the same issue before I open a bug report.

When opening the “more info” dialog on color/RGB lights, the “favorite colors” icons can be long pressed to personalize colors (below)

This works with a standard browser or the HA companion;
however, it doesn’t seem possible to get the long press on the icons with Fully Kiosk Browser.

Can you confirm if you have the same issue?

Thank you!

Long press not working on these icons with FKB:

Found the issue: you need admin rights to access favorite color settings.
Was using a non admin account for wall tablets/FKB.
Case closed.
