I've had an odd bug appear since the initial betas of watchOS 4 all the way through the GM and watchOS 4.1. Specifically, the Inbox on the watch does not appear to properly delete messages from the Inbox unless the app is in the foreground. This seems to happen for both deleted messages and messages moved from the Inbox to another folder.
To be clear: I'm not talking about a delay, whereby once you open Mail on the watch the messages remove themselves. I mean a permanent state whereby if the message was deleted in macOS or iOS, it remains in the watch inbox until you delete it manually on the watch UNLESS the watch happened to have the Mail app active and open at the time of deletion/movement. This also occurs across multiple email providers (both iCloud and Exchange), so it's not a problem with just one specific provider.
Has anyone else experienced this and possibly found a solution? (I've filed multiple bug reports with no response from Apple over the past month).
TIA.
