App descriptions can't be saved because the allowed characters were changed

I wanted to edit (remove donation part) the description of https://apps.garmin.com/apps/7c83d402-4b68-4f0a-b167-7139788a19b3 but I can't save it, because "Sorry, your message couldn’t be submitted because we’re having trouble communicating with our servers. Please try again later." can these 2 things be fixed?

1. allow characters that were once allowed

2. fix the lie in the error message and let us know the real reason
