Why do I get an error saving changes to an item when editing on the featured items page w/ my phone

[JeffR]

We purchase items from a vendor that is linked to Square and will automatically add the item to Square.  Lately (say the last 3 weeks or so), when editing the item via the featured item page in our online store using the classic white Square app on our iPhones, we get an error when saving the item.  It's in pink at the top of the page and says "Something went wrong.  Please try again."

This will happen when editing the title, description, price, etc.

We can go to the Item Library on a computer and edit the item there, save it, and then go back to the app on the phone and edit via the featured item page and it saves without an error.

This happens on both my phone and my wife's phone and happens in both the white Square Point of Sale (POS) app and the green Square Retail Point of Sale app.  Both are the latest versions.

Just tried in my browser on my computer and received the same error (Firefox on a Mac).
