Let's do the experiment.
- Team A and Team B.
- They agree that at exactly 10 am they will take measurements.
- Team A gets a left spin, they know Team B has the opposite.
- Team B gets a right spin, they know Team A has the opposite.
But what information has actually been transmitted? How could a message be transmitted?

If team A takes a secret measurement at 10 am there's no way team B would know what time it was taken?

No there is no way for them to know if team A took a secret measurement.
If either side measures the entangled particle it will break the entanglement, the 'connection' is lost.

Could B team detect the moment a connection was lost?

No. Any detection/measurement results in the entanglement breaking.

No. The only possible way to know there was a connection in the first place is to compare the measurements of A and B teams; if their measurements are strongly correlated, there was a connection.
