I'm experiencing the same issue that this Post discusses and I was wondering if there were any updates on this issue.
Post link - Unable to retrieve feature layers when setting up ArcGIS Connector in Microsoft Power Automate
When I use Enter Custom value and add the Feature Layer Id - 5b442d3f84bd48de84ea2a981fa8a013layerid0 - it appears to connect, but then I can't access any of the Dynamic Content from the Feature Layer even when I use the Fetch Data steps. The dynamic content is not visible and then I get an error message that can connect using the Feature Layer Id either.
I have checked my feature layer and it has the correct settings (info in attached PPT).
The strange thing is there is another user in our organization that does not have any problems accessing his Feature Layers list via the ArcGIS Connectors. He owns a total of 14 Feature Layers and I own 261.
Thanks in advance and any assistance/insights.
Best regards,
