Power Platform Community Forum Thread Details

We have recently installed the Project Accelerator managed app to extend the capability of Project for the Web as detailed here: https://techcommunity.microsoft.com/t5/project-blog/introducing-the-project-accelerator/ba-p/2201000

The install has completed successfully and now I want to customise field choices (dropdown menu options). The page above says:

With the accelerator, everything is customizable. See a field that isn’t relevant to you? Remove it! Want a different set of choices for fields like Strategic Alignment? Great! Change them! Most changes don’t even involve writing code. Just go into the Power App, update the tables, update the forms, and voila! your changes are live"

I can access the choices menu in Power Apps, I can edit the choices in a particular field however, when I try and save I get the message "Request Failed with Status Code 403"

Our IT department has assigned the "Power Platform Administrator" role to me however I still receive this error message when trying to save any amendments to field choices.

Can anyone help?
