I am leaving this here because it was suggested by a Microsoft Support rep to do so:

When maintaining an existing instance of Dynamics 365 with PSA installed, it is sometimes really frustrating when still running version 2.x. Obviously, new features are only released for version 3.x, which makes perfect sense. However, we have had cases over the past months where, after an update to PSA 2.x on a weekend, we returned to the office on Monday and all of a sudden functionality that was there before could no longer be used. Upon opening a Support Request on the respective issues, the only reply we usually got was "Please upgrade to version 3.x as this will solve your problem.".

While I do understand that you want your customers to upgrade to the new version as fast as possible to avoid having to support two versions at the same time, I want to point out that an upgrade within a productive instance is not always that easy because of required coordination with the departments who are using the system and development, who have to verify that customizations still work after the upgrade. Especially in this case, where the default UI changes to the Unified Interface, meaning the upgrade also requires scheduled training of the colleagues who are using the module.

I know that updates can introduce bugs. That's normal. I also know that the focus of development is on the current version. What I do not understand is, why existing functionality is removed without any heads-up and the only offered solution is to move to another version.

I would really really wish that at least an announcement was made that certain functionality will no longer be available (in time before an update) or, even better, that already existing functionality is not removed at all.
