Sharepoint 2016 - "drag files here to upload" misses with certain browsers

Hi experts.

We will soon start using sharepoint 2016. While testing, we discovered that the function "drag files here to upload"

1 is shown in google's chrome for any computer
2 is not shown in IE11 for any computer
3 is shown in MS Edge on any 64 bit computer but not shown on any 32 bit computer
(all machines are on win10 1607, patched. Server is patched, too)

Playing with the developer mode (F12), I found that I can switch the user agent string and the document mode and with IE, switching it from documentmode 9 (why is the standard even 9?) to 11 while setting the user agent to 10 solves it (=displays "drag files here to upload") while on Edge@32 bit, it had defaulted to user agent=edge and switching that to IE11 solves it (document mode: not applicable on edge).

What does that mean?
How to make these changes permanent, modify the client side or the server side?

First off in IE 11 I would enable Compatibility View. (Cog -> Compatibility View Settings)

This setting will stick for users for given sites and can be turned off.

Beyond this you can also create a policy to enable Enterprise Mode for your users browsers and this overcomes many of the issues faced with IE11 and SharePoint.

Hi.

Well, do you run 2016?
Compatibility in IE mode does nothing, no matter what you set. And Edge does not know that
What/how to set enterprise mode?
Enterprise mode is set through Windows Policy.

I've not experienced exactly the same issue in 2016, however I've sene this sort of thing related to whether the browser version was x32 or x64.

What to set where?
The browsers are all 32 bit versions, no matter what OS.

From your link:
"A website that loads in Enterprise Mode renders like it did in Internet Explore 8"
IE8 was not compatible to this function, so this will not work.
I suggest you give it a go. Refusing all assistance goes again the ethos of asking questions in forums.

"Refusing all assistance goes again the ethos of asking questions in forums."
You are right, I might have replied the same to some asker, if I was quite sure that my suggestion could help.
I tried it, it doesn't help.

Did you ever have these drag and drop problems yourself?
Yes I have, but as stated it was not with 2016.

I'm having a look in the community but 2016 being fairly new I'm not seeing specific references to this issue.

News:
After tuning the master page of sharepoint to
http-equiv="X-UA-Compatible" content="IE=edge" 

Open in new window

(before edge: IE11)
It works on most computers, but not all. What's weird, is that the situation hasn't improved for the 32 bit installations, there, still no go in IE11, nor Edge. Works in chrome and firefox, though.

Any thoughts?
Very unusual behavior. Sorry, I have nothing to add that has not already been mentioned.

Best of luck...

Hi Greg.

I will answer anything in the order asked:
1 as we wrote before - only on some after changing the X-UA-compatible tag. Apart from a single 64-one, all problematic ones are 32 bit.
2 Yes, on those machines, it occurs for any user
3 Office 2010/2016 - both affected. By the way, the D&D of sharepoint 2016 at least in IE works with or without office, no matter if installed or not
4 No. All at defaults of SP2016
5 AV was not installed on at least one test machine. Config is the same for all
6 No, we are just starting the test

"Out of the box, everything should just work." - I agree and with any clean installation it just works. We have these few 32 bit installations left, where it does not and there's no reason for it. A clean 32 bit does work.

Right now, I see us using chrome on those systems until we reinstall them some day, but who knows what will not work in chrome. MS docu is very lame about it and only hints that some things might not work as expected, though the latest 2 versions of chrome are always supported.

Though not contributing to the solution, I learned about enterprise mode and time considerable tries to help were made. Thanks you.
