With the 2023 version of QuickBooks coming out, I decided against good judgement to give them the benefit of the doubt and see if Intuit had finally fixed this problem. 

In case you were wondering, they haven't. The buttons at the top still indicate that one should progress from PO -> Receive Items -> Enter Bills, and when following the normal procedure (which also matches real life's paperwork trail) the Bill proceeds to glitch out the "Show PO" button, change to a "Show Item Receipt" button, and then permanently unlink the PO from the Bill. This then leaves a ghost notification every time you enter a bill, but there is no PO to choose from.

The only workaround is to enter the PO, then when you want to receive items create a fake bill and call it "Pro-Forma" or something. Make a Memorized Report to track bills with the name you choose. Now that a fake bill exists, the Receipt will not unlink the PO. When you get the real bill, don't forget to find it among the dozens or hundreds in your Memorized Report, then change all the details of it to match the paperwork.

This is an inane problem with a ridiculous workaround, and it's becoming very clear that Intuit has deprioritized our subgroup of users because the vast majority of QB customers don't turn on Enhanced Inventory Receiving.

We'd love an update from your team that's not a canned response. Please do not tell us engineers are working on the issue without telling us what's the latest breakthrough they've made on the problem.

Here's a video to make this thread easier to follow from the last comment onward.
