WatchOS sendMessage sent only when watch app come back to front

Question

I have a new problem I never met before. I didn't change my app code since Friday, and I have different behavior.

When my app execute a sendMessage, it doesn't works immediately. The message is sent only when the app come back in front.

I use a lot of sendMessage and it worked perfectly since I started my app, several weeks ago.

For information, I just updated my Watch to Watch OS 2.2 this weekend.

Note I have this problem only with my watch, it works fine on the simulator.

Answer 1

I just finished first apple watch connectivity app following this tutorial:

I received the message from sendMessage() immediately. I hope it helps.

Answer 2

It seems really abnormal behavior very, I developed several apps with message passing, never encounter your own abnormal. It is not that you are sending very large messages or've set some particular condition?
