Thank you for the qick reply. That’s the kind of setting I was looking for, but honestly just wasn’t seeing it… lol
Went back through and found ‘Constrain Photosets Per Row’.
Changed from ‘Fix the number of thumbnails per row’ to ‘Fix the padding around the thumbnails’.
Didn’t see the number of columns with an auto option.
Fixes the problem on smaller screens – but now only displays ‘2 up’ on larger screens… Tried adjusting padding numbers, but not having any effect.
Will keep looking. ??
