potential
Push capabililty on iphone 6 with iOS 10 beta 7 is extremely slow.... for Exchange email. Slow as in north of 8-9 minutes slower than the stock email app. Perhaps it is because I am on the beta. But personally do not feel all warm and fuzzy about that. Will come back and try it again when 10 GM is released and/or is out of beta.
Support site/FAQs offer no advice. Again... this version has great potential but for me, I really prefer a stronger push.
