Unable to submit export in console

App Id: 8149FCCE-07DA-F988-FFBB-6154872C9500

I’m unable to submit a simple export from the console. I submitted one almost an hour ago which finished instantly, but the completion notification never arrived. Since then, a second export results in the error:

Another migration operation is already in progress. Please wait until it is complete before you initiate new export operation. 

It is an export of 62 records with no relations.

Thanks

It eventually cleared. Never got a notification.
