Safari download will not replace file when asked
I'm downloading a CSV file from my cloud-based finance system and want to replace the old version on my local drive with an updated file of the same name. Safari has complied in the past, but is now writing a new file with a version number suffixed, e.g.
ss-list-trans.csv
ss-list-trans-2.csv
ss-list-trans-3.csv
I have done the same with Chrome and Firefox and they simply replace the base file as asked, which is necessary as I have Excel references to the base filename.
Has anyone else seen this and is there a way to restore the old behaviour?
