Hi, this PR should be ready. but i would like some input if this should be allowed into the main repo.

Is this code stable? Is the functionality it adds useful/wanted? So far from my testing it works entirely as expected.

Additionally, what should be added to the change log? What should i be testing for in the suggested unit tests?

Hey, apologies for the late response.

The experience for not allowing tax inclusive prices when automated taxes are enabled is intentional mainly due to the side effects on the woo core. The main issue would be incorrect prices since taxes can't be calculated without an address. Even if the address is present, the rate fetch might cause perf degradation. Hence, this PR alone would be insufficient and the change if needed would require a larger change.

Thanks for the review,

Short on time lately so i don't have time immediately but i will be looking into this.

Pardon me if i am misunderstanding, but when taxes are included in the price, the price shouldn't need a calculation, correct? Apart from the itemization of tax entries to be subtracted from the final order total, item prices should remain static as entered in the admin interface. Typically by the time an order is finalized at any point, an address has been entered (for shipping/billing) which is a typical lookup that happens under normal use already.

With that logic, my concern is that the admin and mobile app interfaces aren't automatic, and need to be manually set to an address. But to me it sounds like there is a deeper issue i do not quite understand. Are there any existing issues or documentation i can read on to get more context?

Thanks, much appreciated.
