Hi Lukas, In my testing this works as expected. Would you mind providing the original and new measurement IDs, and I will take a look? As for the wording about subset, I think this could be clearer and I will look into changing the text a bit. But the reason it says set/subset is that over time the probes originally scheduled for a particular msm will degrade (some will be disconnected or abandoned), so you will usually not get all the probes that were scheduled originally, but rather a "subset" of them. Perhaps this could be the reason you did not get all the probes you expected in your new measurement? Kind regards, Stephen Atlas UI

Hello,
when I'm using the "Reuse from existing measurement" probe selection method, only a single probe (the last probe looks like) from the existing measurement is used, not as expected all the probes from the existing measurement. The low expected daily cost is a good indicator for this as well, a part from actually starting a measurement and confirming that it only contains a single probe.
I tried with a new and empty Google Chrome profile just to exclude any interaction with Firefox, browser caches, or the FF extensions I use, and the behavior is clearly reproducible.
The UI also suggest that using a *subset* of the probes selected in a previous measurement is possible, however I have not found a way to actually select probes. The arrow pointing down is not doing anything for me (just endlessly loading nothing).
This could absolutely be an embarrassing PBKAC issue, considering that I just spent an undisclosed amount of time the other day to diagnose why my anchor selection didn't work for the HTTP requests I was trying to run (of course it's not that you can only run HTTP requests from anchors, it's that you can only run HTTP requests *against* anchors as a target...).
Thanks,
