Doesn’t look like it, as this is on Identify and showed an error message. Looks like @theresephillips was able to add an ID, though. Did you have to go to the obseration page to do so?
Sorry folks, unfortunately we had a few brief moments of network lag at our cloud service provider, which led to some brief moments of slower than normal database replication. This can lead to problems like the ones reported here - errors on saving a record, but finding the save ultimately persisted. We’re keeping an eye on it, but for now everything seems stable.
