Thank you for contacting us, and I'm sorry for the issue you are experiencing. If I'm understanding you correctly, it sounds like you are running into a bug that's affecting a small handful of Android users, and we're currently in the process of fixing it. The difference here is, it doesn't look like you are sharing data between different accounts, so it could be this is a different issue altogether. In order to continue the troubleshooting process, I'm going to need to get some personal information from you. Please email us at "firstname.lastname@example.org" and when you do, post here that you sent the email. I'll get back to you as soon as I see your email.
Thanks, Mike! I emailed the support account on Wednesday afternoon. A support ticket has been opened--number 112825--but there has not been any activity on it yet.
