Re-Opening An Older Application, I See No Data Source Icon

[BenDonahue]

Ultimately, my question will be:

How can I reconnect my application to a data source?

Re-Opening an application that hasn't been used in 12 months, I notice that it has no data source icon in the right hand panel:

While researching solutions, I found, from Microsoft, that there are features I need to enable, like "Improve data source experience and Microsoft Dataverse."

Clicking the toggle there produces a pop-up telling me that this feature has been replaced with  "Improve data source experience and Microsoft Dataverse," the exact toggle I clicked:

There were other steps I completed, like turning on "Use display names" and one other when, upon clicking them, the feature disappeared from the features list. I was supposed to waif for a health check, which didn't happen or was too quick to notice, resolve formula issues, save and restart, which I did, but to no productive outcome.

How can I reconnect my application to a data source?

Thank you for your assistance.

At the top of the page click on the View tab and then Datasources. It will show everything that is connected:
