Distant Shore help needed...

I use the Distant Shore app, but in the past week I cannot send message bottles out. It doesn't matter if they are response messages or new bottles. I've emailed the Blimp Pilots, but they haven't responded to my support emails. I receive responses and I get new bottles, I just can't send anything out.

I have uninstalled and reinstalled the app, and I've even rebuilt my iPhone and reinstalled the app and that didn't fix it.

Does anyone have any tips on how I can get support on this?

Thank you!
