Twice I've been stung by this.
The app yesterday showed me that my orders were due to ship today (after the UK Bank Hol), yet when signing in the orders are showing as 1 day overdue. This is so annoying as I am so punctual with shipping. My star seller rating will probably go now due to this bug - so annoying! Has anyone else experienced this please?
Thanks!
It happens a lot with the app, I never trust it fully now and always check on the website.
The app has been weirder than when on my laptop, but all of Etsy is going through some programming updates that are a bit buggy.
Use a browser, not the app, for anything important to do with your shop.
I put my processing times out before a bank holiday, because etsy is a worldwide site, and only ever calculates weekdays.
... and don't forget to allow for Royal Mail strikes in your processing times, and delivery days there is a strike tomorrow, and sept 8th and 9th
