Testers didn't realise that text buttons were buttons
A few participants didn’t notice the “Check connection settings” button. In this case, the “Try again” button grabs the attention and it’s hard to tell that “Check connection settings” is a button, it looks like a text/link.
The same goes for the screenshot on the right, “Fix problem” and “Unlink” look like links. There is a mismatch in these patterns. Use buttons in every case the user is required to take action and use colors to distinguish their importance.
We're using the Material 2 "text button" style for these buttons. Maybe we should use the "outlined button" style instead.

There's also some inconsistency in the colouring: we're using the link colour for the "fix problem" button (like the positive button in dialogs), but the app's primary colour for the "check connection settings" button.
