Although I mentioned this to fiverr several years ago, attachment problems continue to plaque the site. And, if you get an attachment, maybe it appears twice!
It’s an internal fiverr problem, but a good solution is to recommend buyers to place their content information in a zip or rar file and then attach. This works most of the time without problems.
I still like the original Fiverr system from a few years ago as the buying experience was easier, friendly and fast. With change comes the complication of updates that may not work and in this case ongoing attachment problems due to instability. Hopefully in future things will be better.
