Our company has using Data/Analytics with our web app for several months. We have a custom user property 'organisationId', however last week we noticed it has been removed from our tracking plan without any action taken on our part. It does not appear in the list of user properties in the tracking plan, and is not being recorded in user events, despite the property still being posted by the client.
If I try to recreate the user property, I receive the message "Unable to save property. Unable to add property organisationId because it already exists.
The activity log will also not load so I cannot check to see if there were any changes I'm unaware of.
How can I restore the user property? Can we restore the property on all the events that have been logged in the interim?
