If that will not be an issue in the final version, then the enigmatic error message is probably irrelevant. But in general error messages should be as clear as possible. In this case, it is only my guess, based on Nick's note, that this is an SSL error

If these new MailWasher accounts for Android are a run up to yet another business model, with an annual subscription to keep the account, then you are going to have to be very careful in how you present it, especially to people like me who have bought a "lifetime" version of PRO. It does not take much to upset customers who are used to one approach and have to change to something unfamiliar.
