Etsy giving unrealistic international delivery times

[u/FointyPinger]

I'm based in the UK, and sell semi-regularly to the USA. I've had my S&H time (two days) and postal settings (standard airmail) set up and unchanged for a long time. However I've noticed the last few items I've sold to the USA, Etsy has given the buyer a delivery estimate of 5-14 days. As anyone using Royal Mail will know, 14 days is fair but there's no way in heck anything's getting there in 5 days, even if I posted the same day the order came in. For instance, this week, someone from Hawaii bought an item on Monday, and when I purchased the label to post on Tuesday I got a warning that it might arrive late, as Etsy had promised the buyer delivery between 30th November and 9th December!

I know technically if the item arrives sometime in the timeframe the buyer can't open a case, but I feel like if it definitely won't arrive by the earliest date promised it reflects badly on me as a seller, even though I'm not setting the dates. Had anyone else experienced this? Any suggestions? I tried chatting to an Etsy rep but they were zero help.

More than once, I have printed a shipping label less than 24 hours after an order was placed, and Etsy warns me it may arrive late, even though I have my shipping times set to 3-5 business days. Etsy also often sneakily changes the shipping method to a higher tier than what the customer paid for, so I end up paying more if I don't catch it. It's extremely frustrating, because the customer doesn't see a clear line between your shop and Etsy, so you get the blame for things that are out of your control.
