Multiple overlapped windows asking for credentials are shown.
In Power BI Desktop we use Organizational accounts (OAuth2) to get data from OData endpoint.
After May, 2022 update, when connecting to the data source first time or from a new machine (no credentials are stored in Data Source Settings) user is asked for credentials by dozen overlapped windows:
Originally there was only one window where user can select account type and provide his credentials.
Now there are multiple windows on the same position asking for the same information.
Even if user selects his account type and provides his credentials into the top visible window, he has to repeat it several times, before all windows that are asking for same credentials will disappear.
Once credentials are saved in the file or globally for the Data Source - report can be refreshed normally.
