I'm trying to sharing a PowerApp to an external user from my organization and I have the following error:
The PowerApp reads the data from an Excel hosted in One Drive for Business through a flow, in one account related to the tenant @xxxx.com. Then, I shared the app and the excel file to an user @yyyy.com having a BadGateway error.
It is not exactly clear what the limitations are while sharing apps this way. In section "What connectors support guest access?" the currently supported connectors for guest access are listed. It seems that a lot of connectors are not supported at this moment, including Common Data Services (CDS).
Am I correct to assume that there is no way for a guest user to ineract (=create, read, update) with CDS data in a Canvas app?
