Hi Terry thanks for posting in the community! Apologies for the trouble you're experiencing. Could you try opening your document in a private or incognito window to help us narrow down the potential cause? Could you also try connecting to a different network if you and your colleagues are using the same one? Sometimes account performance issues can be related to internet security/speed or browser issues. These steps will help us eliminate that possibility.
If those don’t resolve the problem can you please let me know if this is occurring in all documents where you're using conditional formatting or just this one? Additionally could you please specify what in your screenshot is not loading or missing? Are you looking for text within the blue and pink circles that are empty? Or are there conditional formatting rules that don't seem to be applying entirely?
Thanks in advance for your help and patience!
