When attempting to reference a Capacity Reservation Group across subscriptions MAPI fails with the following error.

failed to create vm tst-redacted-northeurope1-rhjzl: failure sending request for machine tst-redacted-northeurope1-rhjzl: cannot create vm: compute.VirtualMachinesClient#CreateOrUpdate: Failure sending request: StatusCode=400 – Original Error: Code="BadRequest" Message="Cross subscription association with capacity reservations is not supported for api versions below 2022-11-01."

Unfortunately it looks like fixing this would require an Azure SDK bump as v0.68 does not include references to the API version mentioned above.
