Still in submitted status
Same here for 02-Apr application.
Called IRCC multiple times but only heard that the application is in progress.
The inspect tool says "Your photo attachment has a technical error and cannot be opened/reviewed. Please review and correct the attachment before re-submitting. Please note, not all file types are supported."
It was a JPEG photo, so not sure what might be the issue.
However, the agents did not mention anything in any of the calls about this status during the calls.
