Sending data from android to watch is too slow !

Hello,

I developed an AndroidApp that sends messages to a WatchApp I also developped (on a fenix 6x pro).
The WatchApp makes my watch rings when a message is received.
The AndroidApp uses "connectIQ.sendmessage":

connectIQ.sendMessage(garmin_device, garmin_app, message, new ConnectIQ.IQSendMessageListener() {

The WatchApp registers to "PhoneAppMessages", like this:

There is 2 to 3 seconds of latency between sending and receiving, and it's critical for me. (to evaluate the delay, I put the time in the android message, and I compare it with the time of reception).

Please, could someone give me a solution to delete this delay ?

Thanks in advance for your answers,

mike
