hi! flow concurrency is disabled on concurrency based plan?

Hi Ruslan! The ability to set your own flow concurrency limits is a mid-tier feature on both the old concurrency based plans and on the new plan structure ( so currently custom concurrency limits are only available on the Standard Plan and above)

Sorry it is not clear. I have got flow label. 5 flows with this label. I want only 1 flow to be able run in same time. How to configure it?
