Forerunner 245 M does support skipping last recovery of interval session.

I have a strange issues with my FR245M.

A couple of weeks ago I notices the possibility to skip the last recovery phase of the last fast session.
I only saw this on the webversion of connect, not in the app and also nothing special on my watch.

During my training it worked as expected. Last fast session followed by the cooldown.

Two days ago I made a new workout on my phone and while synchronizing it with my watch I got a notification that my phone doesn't support this function.
(And the check box has also disappeared from the webversion of Connect.)

And indeed, during my training it went from fast session to recovery and then cooldown.

What is going on?
