Advanced Card disappeared with November update

Regarding the graphic error - they changed the default styling of the new card visual and those changes might have impacted how your visual is being displayed too. It's quite annoying, but I'd honestly recommend to just rebuild the card from scratch, so you start with a blank slate with all the current default settings, then style it the way it again so it looks like you had it before the update. You could also try and reset all the individual settings to the default-state first, but starting from scratch and re-style is probably the more efficient option (unless you had any Bookmarks set up that would impact the cards). 

The New Card visual was in public preview until now and just became GA with this November Update. Since it's GA now, I would hope that there won't be too many breaking changes like this in the next updates.

Thanks KarinSzilagyi , I was hoping I could avoid rebuilding the visuals, but obviously I have to do it. Good to know that the card is GA now.
Thanks for your support 🙂
