Everything works as it should for iOS 10 and lower, when we updated version for iOS 11 we have a strange crash only on devices:
Cannot remove an observer <CBPeripheral 0x1c03127e0> for the key path "delegate" from <CBPeripheral 0x1c03127e0> because it is not registered as an observer. Discovered CBPeripheral is my mac mini device, and he is not on a list on your cloud.
I started digging, and it only happens when
ESTBulkUpdateris turned on, doesn’t matter if i am using
start(withCloudSettingsAndTimeout. Can you investigate it please?
