sendReliableMessage not always working

[radefffactory]

I noticed that sometimes sendReliableMessage for Real Time Multiplayer doesn't work. And that causes my game to stop working. I tried to avoid this in onRealTimeMessageSent with: if (statusCode != GamesCallbackStatusCodes.OK) { //send again due to error sendMessage(lastMessage); } but this doesn't always work. Sometimes it tries to send the message again and again at least 100 times and sometimes the game continues, but sometimes it drops the player trying to send the message. How I can ensure that the message delivery is always successful? This is very unreliable now. Does other people face similar issues?

I notice that this is happening since last Monday - and that is the day of the last Google Play Services update.

I'm having the same problem and it happened when I imlemented my game last year not only recent updates from Google Play Services. I'm using version 12.0.1.
