HI @Polypody-9. Can you tell me the full model number of your Tab and the Android version you're currently running? Can you access your email on a web browser?

Thanks for responding.  I have finally resolved the issue by stopping the App, then immediately powering down, before restarting.  Now all ok.  The key thing seemed to have been the immediate powering down.  No further issues.
