Did this start happening just after you updated ? Thanks
Yes, it never happened before with the older version
As i am using a old version i cannot help you . Let wait for the developer to respond
Tim Iām guessing the older version he mentioned is not the same one we are using. Probably one version before the update.
i did notice today too and one other thing when notifications are coming one or two at the same time and when you have a call, it disappear right away and you just have the las one. its pretty weird .
I do not know what may be happening to you, since more than 90% of users have version 13.1 and I have not been complaining about old notifications or a situation like yours.
Try uninstalling and reinstalling the two applications on both the Smartwatch and the phone.
You right, i just realized now thereās a version 13. I was using the apk that youāve shared in here, version 12. sorry mate @lumaticsoft 
Now Iāve been using this version 13. So far no delayed notification, but i forcely to return to version 9, since in this version 13, once both device got disconnected, it wonāt automatically reconnect though Iāve turn the automatic reconnect option.
Is there any way to view the playlist on watch while playing music on phone ?
I am using version 9.0 on all my devices. On my Lem 10 when I turn on the app I now get an overlay message on the screen that says, āValid version until only 11/20/2019 update the application.ā The message goes away and the app still works. Is there some reason this occurs with this app? It is not normal in my experience with any other app.
Mine also . Dont worry about it 
Donāt worry, itās a version 9 message. I never thought that this version would be one of the last ones that would have many calling functions and thatās why many users wouldnāt update it.
Also do not worry that it will work without problems, if the message bothers you a lot this installs version 9.1
Phone
Smartwatch
Have you ever thought about an unofficial development of V9? A development that is not sold through the Playstore?
Or a non-official add-on with the phone features that work with the latest version?
I think thats a great idea 

i believe that its call development edition. like alpha or beta, still in progress, yeah good idea. lumaticsoft, what do you think?.
Yes of course @G1NT0N1C because I bought kospet Hope for bluetooth calling ( after seeing one of his advertisement page ) . I donāt know what google is protecting us from ? facility or fun.
This is my desire too. Please provide us with such unofficial development of app, which includes all recent features as well as calling feature like version 9.1.
Hopefully, we remain waiting for.
I would really like to be able to do this but unfortunately I cannot continue to develop 2 versions at the same time, I have lost a lot of code and would have to rewrite many functions that are developed in version 9 in the new version.
In addition, it becomes increasingly difficult for me to give the correct support to all users and with two different versions it would be almost impossible.
Too bad and sad, but itās what itās. V9 the best,i donāt really care about Bluetooth calling, replaying messages itās more important .
