Help samsung s5 update

[Android Question]

I have a Samsung s5 I did an update on yesterday & only problem I see is that when I open Gmail everytime with out fail it closes everytime & leaves a message bar saying unfortunately Gmail has stopped. I can't even look at one email without it doing this. I updated to Marshmallow 6.0 on 6/4/2016 any ideas for fixes or what do I need to do?

It's good practice to boot into recovery and wipe your cache partition after a large update. I usually preform a factory reset and start over fresh but most get by with wiping cache. Helps to get rid of any left over junk from old OS.
