I wanted to enrol in etsy payments and needed to add my GSTIN (taxpayer ID as an indian seller) but the legal shop information edit button is un-clickable.
As etsy have put my shop on holiday mode because i didn't receive my taxpayer id till their given time, I cannot chat with any agent from etsy support. I emailed them and they just keep sending me automated emails which are of no help.
Your only option is to email. Make sure you reply to the same automated email with "I still need help". Do not start multiple emails as these will be rejected.
