I am following Lisa Crosbie's excellent tutorial. Everything was fine until I reached the point where I had to import the data from Excel. When I select this option, my screen flashes, and nothing appears. I tried a different environment and changed the browser from Chrome to Edge, but I still faced the same problem. I have no issues with pop-ups, as I am not blocking them. I even tried to create a simple app and import it from Excel, but I faced the same issue. Basically, nothing related to Excel (import or export) works, as I cannot even see the screen to select a file. Can anyone help or recommend a step I should take to solve this issue? Thank you.
