Hi @Jon Kvalø
From your description it seems you've been importing oData data into the Data Model straight from Power Pivot (if this isn't the case, please clarify):
TBH I have no idea which oData versions are supported by Power Pivot. However - AFAIK - the oData connector for Power Query/Get & Transform and Power BI supports oData v4
So, instead of connecting to your oData feeds from Power Pivot, proceed as follow (summary of steps) - from Excel:
- Go to the Data tab > Get Data > From Other Sources > From oData Feed
- Enter your url > OK
- Select your table(s)
- At the bottom of the Navigator window > Click on the arrow down next to Load > Load To... > Check options Only Create Connection + Add this data to the Data Model
