Gear S Email Issue ...

Problem: My Gear S is not receiving email. I am able to send email from my Gear S just fine though.

Everything else seems to be working ok: Phone, News, Weather, Opera, Games, apps. I can both send and received Text Messages. Only problem seems to be that I cannot receive email.

Has anyone else had this same issue ?

Both Samsung and T-Mobile Tech Support cannot help. T-Mobile is sending me a new SIM card to test and see if that resolves this issue .....
