Custom Thumbnail for locked album sets?

Previously in CE4 I was able to use custom thumbnails for the cover image in my LR publisher protected client album sets. Doing so now results in the missing image icon being displayed. Is there another option or am I doing this wrong?

See https://studiothomasphoto.com/clientaccess/

see if this helps

So I set that setting to “no” from the default “yes”, nothing has changed.

The protected album does not show in the album set here https://studiothomasphoto.com/clientaccess/modern-luxury/

The protected album set does not show in its parent album set here https://studiothomasphoto.com/clientaccess/

I see thumbnails at those links.

Looks like you need to upload larger custom thumbnails for those large squares, but otherwise looks good.

Be sure to clear browser cache

Yeah, I’m working on that. will have to republish everything once I get all the templates correct. Going well though.

yup clearing the cache worked, user error once again! Thx!
