At the company I work for, the executives rely on MANY Power BI reports, which were built by colleagues or myself, over the course of years; these reports are connected to dataflows or semantic model...
Based on the information you have provided so far, it is not possible to determine the exact cause of the slow refresh. You will need to provide more information:
1. Are there a specific few reports that are experiencing slow refreshes or errors or are they all affected? Do they correspond to the same data source or different data sources?
2. What data sources are associated with the reports that are having problems?
3. I see in the screenshot that there are a couple of refresh errors, what are the specific error messages?
