I cannot get my Etsy dashboard and selling page to load at all, whatever I try. I am in the UK and use an Apple Mac computer. I am unable to list anything or make any changes to my to my shop.
Just a thought, and I may be completely off-piste here, but have you checked your spam box for emails from Etsy? I wonder if they're looking at the bottle tops for 'infringement', as some of the names on them may be trademarked. Alternatively, have you checked that all your financial are correct, and that your bank details haven't been compromised?
This would not prevent the actual page loading.
It sounds like it is an issue your end so clear your cookies and your cache and/or try a different browser. I use Chrome, Edge and Vivaldi and all work well. Firefox is apparently suited to Etsy but it always hangs for me so I don't use it.
I have never had a problem before until a week ago. I use Firefox.
