Newton on iOS and iPadOS fails to update email#763

Newton is not updating email on my iPhone and two iPads. I see notifications of emails in Notification Center, but those emails do not show up in my mail window. This updating problem does not occur on my MacOS devices. If I logout and login, the iOS and iPadOS devices will update for a while, but stops updating a few hours later. It was this problem that led me to discover the login problem that NewtonHQ eventually fixed for us. <SIGH>. Anyone else having this updating problem?
