Anyways, in the meantime, the only thing we can do is pretend that button doesn't exist and instead direct users to the marketplace to install. Except, since our app is only installable by G Suite admins, if you happened to log into your personal Gmail account first, our listing is not even visible...
Google's whole account situation is a dumpster fire - and don't even get me started on the APIs they have on G Suite, that seem to have grown organically out of an 'admins would like to script a bit with the data'-use case and only added 3rd party apps as an afterthought. I wonder if the G Suite team is just chronically understaffed and underfunded or if they just don't realize how broken the whole thing is.
Don't lose hope, we filed a similar request and then forgot about it. Several months later, we got a response and the issue has now been resolved. Good luck!
Turns out it's something to do with enabling support for the activity log or something. That was a fun few hours.
I also love how no matter what Google site I'm using, it's signed into the wrong account. It's almost comical.
Having recently been burned by this, I can wholeheartedly agree. The list of features that don't work if your Google account is not "@gmail.com" has caught me out so many times. The problem is even worse if you are an Android user and have a bunch of app purchases tied to a non gmail google account - as I recently discovered when trying to add my old Google Apps (custom domain name) based Google account to our Google play family plan.
The lack of documentation on what works/doesn't work is staggering as well.
However, the stacks (ecosystems) need not be mutually exclusive. For example, Microsoft's ecosystem includes dozens of apps for iOS and Android, and it has supported Macs for as long as Apple. It also has Linux options for Windows 10 and Azure.
Apple mainly supports Apple hardware, but it still has iTunes and iCloud support for Windows.
That's not your account, the google photos app doesn't support AndroidTV natively, only casting is supported.
And it just might work, if any of the newer Google experiences worked on all Google accounts.
My experience as a Google Apps / G Suite user, is that few to none of the newer Google products and features are either available or offer anything more than a basic and perfunctory service.
"One account, all of Google", not if the account isn't a Gmail account.
It's the biggest thing that is broken at Google, and it's broken in every product department, every team, every feature.
It's also why I haven't purchased a Pixel (why? When much of the benefit I'm denied access to, I cannot even ask Google Assistant for my agenda), and I haven't purchased a Home (why? When again it is limited and locked down), and my Android TV seems to lack integration with Photos (which I assume is because of my G Suite account but maybe it's just crappy).
Google accounts seem to be driving towards 2 very different and polarised futures, a personal one and a professional one. Having only professional accounts means that all of the personal features are unavailable.
