Previously, the activate changes mechanism could incorrectly indicate that changes had not yet been applied, even though the activation had already completed successfully. This was caused by insufficient waiting time and unreliable status checks during the activation process.

We increased the timeout and improved the status verification logic to ensure that the activation state is reported accurately. No user action is required.
