Good day Edward,

Thank you for sharing your concern.

Based on your description, this appears to be related to the SharePoint list not loading in the Power Automate dropdown rather than a permissions issue. In some cases, the dropdown may time out while retrieving available sites or lists, causing certain items not to appear.

As a workaround, you can select Enter custom value and manually provide the SharePoint site URL or list name instead.

For more information, please refer to the Microsoft article below: Dropdown list doesn't load items in triggers or actions in Microsoft Flow - Power Automate | Microsoft Learn

I hope this helps clarify the behavior.

Dear Edward,

Thank you for your time and for the effort you have put into troubleshooting this issue.

I apologize that the troubleshooting steps I provided didn't fully resolve your issue. For more specialized assistance with Power Automate, I recommend posting your question in the Microsoft Power Platform Community Forum, where experts and community members regularly share their knowledge and experience.

As the forum is dedicated to Power Automate and the broader Power Platform ecosystem, it can be a valuable resource for detailed technical guidance and solutions to similar scenarios.

Regarding the "Reload site?" warning, this message typically appears when the page attempts to refresh while there are unsaved changes in the answer form, such as when you are adding or editing a response.

Thank you again and I wish you all the best in finding a resolution.
