Starting last night, when I try to log into Etsy (I'm using a web browser; not the app) there is about a 30 second delay before the log-in pop up window will appear. After inputting my credentials, there is an even longer delay before the website will load. Today it took about 5 minutes between logging in and having the website load. I'm assuming others are probably having this same issue.
I don’t have the issue. Try resetting your modem
Try using a different browser and/or clear your cookies and cache.
That may be due more to your modem or WIFI. Try rebooting. Check your ISP. If you are in an area that has heavy weather that can affect. Also brick buildings can affect WIFI.
I have small issues from time to time. It's my ISP and not Etsy.
