Data upload problem - Not validating data


I am trying to upload data as .CSV, with a ; delimiter. I select the file, then the field and ; as delimiter, but when I click on Validate it just keeps processing (as below). It just goes and goes and goes - keeps going up. Nothing else is happening.

Can anyone tell me what I am doing wrong here?

Can you share the file? And ideally make the app open to see the data structure. Otherwise no one can really help.

Did you ever resolve this?

I don’t recall I’m afraid. Can’t even remember which app I was working on at the time.
