Exclamation [Q] Gmail Invite "Describe Error"

Hi Dev's ,

For whatever reason, I can't accept any invites on the stock GMAIL app. I receive this "describe error" message once I press on the invite.

Message me for screenshot (can't post yet)

My phone is a Galaxy S5 on Verizon
Android Version 4.4.2
Official Firmware

Does anyone have a fix?

Thanks in advance.
