Direct links (categories) not working

Hi, yesterday our direct links for appointment categories stopped working, and we get this message:

I've reached out by submitting a help request but had no reply. Does anyone have any tips to fix this?

Thanks, Stuart

High Stuart, i now how the same problem.

Did you manage to fix yours ?

If so could you help me out please ?

Hi, yes the support team found a workaround - we were using special characters in the name of the appointment group - e.g., 1:1, and so we took out the special characters and it now works - e.g., 1 on 1. I believe it is something to do with an update to Acuity Scheduling that has been implemented.

I have the same problem, no special characters. I am in a pickle... I reached out to support for help. Anyone else have recommendations to fix?
