Contacts - cannot seem to populate the csv file of contacts into the app

How to get yrs of contact data into "contacts" app wihout having to do individual entries. Just worked by chance the first time and now cannot get it to upload the data from a CSV file...tried a link but just cannot get contacts populated.....My apologies - just does not show any processing so assume nothing is working but has repopulted the contacts - just takes a Looong time as there are many contacts - many thanks no support required!

Is the csv File detected and can You choose it?
