There are some issues with the feature of dynamically selecting a pool. Basically I switched pools the other day, and I did it from the dashboard instead of changing the order in the pool in the settings and restarting.
The first issue was that I had to click the "Select This" button twice. The first time didn't seem to do anything. Or at least it didn't show any differences in the pool selection in the dashboard.
The second issue is that last night the pool that I dynamically selected must have had a connectivity problem. When I woke up this morning, the rig had switched back to the first pool in my settings, not the one that I had dynamically selected.
Already reported the first issue in the thread, I confirm it's really difficult to select a new pool.
The second issue... I don't think it's really an issue, I think it's the default behavior, and I find it better to be like this

But it would be nice if we could opt for what we want.
