This question is not a duplicate to another question that asks about the same message, but in another context. The context of this question is just about uploading screenshot images and getting the message.
Today, I had a new message when uploading images to App Store Connect:
Invalid GeoJSON: Your routing app coverage file is invalid.
This makes absolutely no sense since, at this time, I had not even chosen a build for the upload.
Retrying to upload the images, it worked. But unfortunately, the message appeared for each language and format.
Is this a bug by Apple or am I missing something? I would guess that uploading images has nothing to do with GeoJSON.
I used Safari. Others seem to have the problem with Chrome. So it occasionally seems to happen on all browsers.
