I'm sorry that you're having trouble using your in5 content with Google Analytics that's hosted on a Tiiny Host site.
It sounds like your issue may be a support question for Tiiny Host, though. I can see from their support content that they automatically include another built-in analytics platform:
And they support Google Tag Manager which is different from Google Analytics:
I'm also curious your University not being handle the in5 Plugin -- was it in5 plugin for InDesign or the in5 WordPress plugin? And was there a technical issue or something else? I recall your University had an issue with the version of PHP it was using with WordPress. If that was the issue, the in5 WordPress plugin works with PHP 8.2.
