Get error when trying to change pools

When i try to change pools to core.pool I use these instructions:
Go to the “Pool” section. Click on “Connect Pool” radio button and paste our pool link there:

And get this error:
Cannot join a pool while waiting for target state:

I’m guessing, but it takes time to change pool, iirc 50 blocks .
So I’m guesting, your in the waiting period and so can’t re instruct another change.

I could be completely wrong having never pooled, but thats my best guess.

Id wait and see.
