They’re scheduled, so maybe it was just time to run. Clicking it on the series details page will run it for that series, on the list of all series it will refresh all.
Not sure how much effort it’d be, but it’s not something we would do, it’s unnecessary in almost every setup, except yours for some reason and would lead to it being set without people understanding what it does (we already see that for other settings).
Since it loads at the 210 second mark every time I get the feeling there is something on your side causing that delay, because CF is unlikely to allow the connection to sit idle that long which would eat up resources needlessly (it’s a benefit for them to terminate it immediately). I don’t know what the significance of 210 seconds is, that doesn’t ring any bells.
Since you’ve replicated the behaviour in powershell are you able to replicate it on another system on your network? I’d also be curious if you can replicate it with another network connection (cellphone acting as a hotspot) to rule out your router/modem/provider’s infrastructure.
