A new problem just started happening with email notifications. The watch lists them just fine, but when I open one and then clear it, all of the other emails clear from the watch. This does not happen with other notifications (texts, calendars, etc.). Any ideas how to fix? I'm using an iphone XS on 13.5.1. This is annoying because I either can't clear just one email without deleting all the others, or I have to leave them all on the watch and clear them all from the phone. Thanks.
