I want to use the auto synchronization. I uploaded an test excelfile to the server. It's a small table with Nr, name, surname with 3 entries. To insert the link I used the browse button. When I click on fetch data it changes to the format settings and didn't load anything.
I'm using Joomla 3.8.10 with php 7.8.1.
What am I doing wrong? Does the sheet need a specific name?
