Applying "Horizonal Distribution Space" resulting in objects spread outide the artboard, and sometimes outside maximum canvas area depending on which "Align To" option is selected, but non of them result in the intended outcome.
I've checked for stray points inside each grouped object Im trying to distribute, nothing should be causing this outcome.
Unfortunately the file is for a design client and cannot be shared here due to intellectual property restrictions.
Anyone else experienced this on Illustrator 26.5 for mac?
Speaking only for myself, no, I have not experienced this, nor can I find a way to replicate it. You've said "not working (again)": does that mean again in this document, or has it occurred in others? Beyond checking for stray points, have you restarted Illustrator/rebooted your computer? Reset preferences?
