For some reason, when I check buyer request on my laptop, I can see just 1 attachment in buyer request but same thing when I checked in mobile app, there are 3 attachments for that request. I was actually sending proposal for it and they also mentioned in job post CSV2 however I was not able to see CSV2 and in proposal also I write that. But when later I checked on mobile app it was there.
You can check screenshot for reference.
I hope fiverr technical team will look into this matter and resolve this as I think this is crucial while sending proposal.
