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, Lukas
