I have the options of standard, 2 day and 1 day shipping options for all my listings. I have noticed in the last few weeks, very few premium shipping orders, so I started to take a look. All the shipping settings haven't changed and are still active, but when I go to any listings, it shows the delivery time frame as normal for the standard shipping, but where Amazon shows the "or get it faster by XX if you order within XX" is showing like a week out instead of showing it could be delivered in one day from now.

The only thing I can think of is that it's picking up my normal handling time for standard shipping which is 2-3 days and then adding just the one day on top of that instead of the premium shipping options showing same day handling time if ordered by 2pm as Amazon states should happen. Until recently, it had been working as normal, but wondering if anyone else has encountered this issue?

It's important that customers who are scrolling through items to see they can get mine in as little as a day as they are personalized and sometimes people need them asap whereas personalized items normally take some time to prepare, but I offer rush orders that had been doing very well until now.
