What Traccar version are you using?
Hello, sorry for responding so late, I am using traccar version 5.11
You have to upgrade. Firebase deprecated some old APIs we were using, so it's probably related to that.
Ok, I understand, one question, do I just have to update the version of Traccar or do I need to do an additional configuration?
Just the version I think.
Ok, I understand, thank you very much for the help, I will update as soon as possible
Update, hello, The update was made and the push notification functionality was recovered, thank you very much for the support
Hello, greetings, I have modified and customized the traccar manager application and I had push notifications activated via firebase, but out of nowhere they stopped, traccar service generates and locates the vehicles but they no longer send the notifications, I tried the chanel test option and The test message is not sent, for any suggestion or help to solve this problem I am very grateful, PS sorry for my terrible English
