I'm submitting a new version of my app, and after click "submit for Review", it shows "Unable to Add for Review: There are still screenshot uploads in progress." However, these screenshots have been in progress for many hours. I tried verified that it was not a problem with the screenshot files, as I deleted and uploaded screenshots that had uploaded and been approved in previous updates. I also verified this behavior is happening across multiple apps. Therefore, I suspect that it is an issue with App Store Connect's server. I have been waiting all day for this to be resolved - hopefully someone can fix this ASAP as it is a blocker to submit any app updates and I have a critical bug fix that needs to be approved.
