Yes there is a build selected. By uploading the build i got the mail from Apple Store Connect with this message: ITMS-90078: Missing Push Notification Entitlement
but if I have read correctly in the forum, this can be ignored
I have a build seleted
for each language there are 2 Screenshots in App-Previews and screenshots for all devices and so on.
I don't see any errors.
The mail is not important you can ignore it. Check for a red warning part in the page, sometimes it is hard to find, maybe it is in the other page like price and availability or other.
