(iPhone 9 on public ios9 and watch on public watch os2 now) The main account I'm concerned with is for work and is a gmail account. I have the gmail account added to my apple mail app on the phone and watch but results are underwhelming. I have gmail mail app on the phone push an instant notification to my phone but obviously you can't click the notification to be taken to the message because there is no gmail mail watch app. So I push the crown, select the apple mail app icon and it will load the subject, who it's to, and many many times it will say unavailable to view full email on watch. Continue on phone. This is just for basic, no picture emails, but they are usually several replies per each mail. So the stock mail app isn't that good for this case. I've tried spark, and have a hard time with it actually downloading the message on the watch, it will have a blue bar like it's loading and usually never loads, even after 2 minutes of screen tapping to keep it awake. I've tried 'tl;dr' and I get a pin wheel off app load and will never go further. I've tried 'mymail' and the app loads but even after set up, will never receive my new emails to its inbox. On ALL those mail apps I've listed I've tried removing them from watch and re installing and it's the same results for each one listed. Anyone have any suggestions?
