I wanted to change the description of https://apps.garmin.com/apps/7c83d402-4b68-4f0a-b167-7139788a19b3 and I couldn't save it. Even when I don't change anything, just click Edit Details and then the Submit button I get the following error message:
"Sorry, your message couldn’t be submitted because we’re having trouble communicating with our servers. Please try again later."
I was able to do the same for other apps, so my guess is that it's something to do with special characters in the description. But obviously this is a step back, as I was able to save the current description earlier.
PS: Maybe you could add something like "Developer Dashboard" or "App Store" as category.
