Problem with recalculation of resource units

Thank you RodFromm, 

I did not know that the scheduling mode can be configured on the organization level. But it seems this only regards "Project for the web". https://support.microsoft.com/en-us/office/change-the-task-type-for-more-accurate-scheduling-b0b969ad-45bc-4e9e-8967-435587548a72#:~:text=the%20task%20type-,Overview%20of%20task%20types,uses%20fixed%20units%20by%20default.https://support.microsoft.com/en-us/office/change-the-task-type-for-more-accurate-scheduling-b0b969ad-45bc-4e9e-8967-435587548a72#:~:text=the%20task%20type-,Overview%20of%20task%20types,uses%20fixed%20units%20by%20default..

We use Project Online and its Desktop Client and I can't find this configuration on the organisational level (at the PWA settings), but only in the desktop client: I can change the default task type for the project and the task type of any single task and I can even add the column [task] "type" and see my changes being applied (as described above). But after I make changes to the values (units/duration/work), the recalculation seems not work as described in https://support.microsoft.com/en-gb/office/scheduling-modes-in-microsoft-project-for-the-web-b2d1626b-8dca-40a1-922e-fbaffd56e589#:~:text=There%20are%20three%20scheduling%20modes%20available%20in%20Project%3A,mode%29.%202%20Fixed%20effort%20%28Work%29.%203%20Fixed%20units. to the currently selected mode/task type, but to the mode/task type in which the task was created.

Since changing the task type / mode and the effects are https://support.microsoft.com/en-us/office/change-the-task-type-for-more-accurate-scheduling-b0b969ad-45bc-4e9e-8967-435587548a72#:~:text=the%20task%20type-,Overview%20of%20task%20types,uses%20fixed%20units%20by%20default., but this does not seem to take effect on the recalculation, I would consider this a bug. But maybe I don't understand how it is supposed to work or I am missing some settings (maybe there are also some configurations on the organization level for Project Online as well).

Regardless of this being a bug or a feature, it would be helpful for me to know if it is possible in Project Online Desktop Client to recalculate the resources units when changing the work/effort without changing the duration / schedule of tasks, that were created with the task type / mode "fixed units". My current workaround would be to recreate all our project plans, which would not be desirable due to the amount of work...
