I cannot upload screenshots for a new version of my app. Is there any trouble on app store connect right now? Both screenshots for 6.5" display and 5.5" display are unable to upload. Error message says it's wrong format, but the resolution is correct and these are PNG. Files that could be uploaded in previous versions also cannot be uploaded.

That was my mistake. The file name should have been ".png" instead of ".PNG". But I had no problem using "*.PNG" until last month...
