Since the last software update on February 28, 2017, push notifications on my exchange account appears to no longer be working regularly. Emails come in anywhere from a couple minutes to 5 hours later. This is occurring only for samsung s5 users within our company that installed the last software update. Those who haven't done the update are not having issues. I have spoken with Verizon and Samsung, we have checked our company server setting and even completely reset a couple of the phones. I am not seeing this issue reported at Verizon or Samsung, however I did notice that reviews on several third party email apps are all commenting on similar issues with these push notifications. Can someone please look into this and help us find a solution other than manually forcing a send/receive/sync all day every day, which causes battery to also drain faster?
