Hi Brion, thanks for your question! Please try to copy the Activity, and then save the copy. We had a release go out, last night so perhaps one of the fields of your draft Activity did not get migrated properly. Hope this helps!
Thanks for the quick reply. I made a copy of the activity in question. Unfortunately, that didn't fix the issue. I'm still getting the Error: Invalid Fields when I attempt to Save or Save Draft and Close.
Is there anything else you can think of that might be causing this?
I've even gone so far as to create an activity from scratch, which presented a different set of problems. Like experiences disappearing after they were added.
Thanks for sharing your experience and apologies for the inconvenience, this must be very frustrating! Your best bet at this point would be to submit a ticket with client care so that we can take a look at it as soon as possible. Just send an email explaining the issue to: email@example.com. Hoping this gets resolved asap!
