What limitations of reporting should i expect with an independent watch app on Apple Connect?

I have noticed that with an independent watch app on Apple Connect, that I don't get the same Analytics reporting. For example on the "Overview" tab I don't have a single piece of data for "Sales", "Sales Per Paying User", "Sessions per Active Device", or "Crashes".

Digging deeper into "Sessions" I don't have any data there at all.

The App has been launched for over 90 days, and I can verify through other sources that I should have some data in these categories, much like I see for iPhone apps.

Please advise on what I should expect here.
Thanks,
