I have been using AM with my work Exchange account (with EMS setup), and recently added my personal Yahoo account since upgrading my device to Android Lollipop 5.1, where the stock email app (as well as the Gmail app) renders the Yahoo in-message text size way too small, for reasons unknown, and it's not adjustable.
The issue I'm having has been occurring even since originally using AM with only the Exchange account. Simply put, probably at least 50% of the sync attempts fail (for just the Exchange account). But what's even more curious is that, if/when the sync attempt fails, I can touch the sync icon next to the account name and it will sync successfully in two seconds (or less) almost 100% of the time! So I wonder what's going on with that. I have the sync interval set to ten minutes.
My general question is also about syncing. Is there a way to have separate account-based settings for the Time Reference point (as opposed to the global app setting)? I like a ten minute interval; I'd just like to stagger the accounts' sync points while maintaining that. I've looked where I thought that'd be logical to find (the Special Settings area of either account) but apparently that's not currently a feature.
Not a deal breaker, but just asking. Love the product!
