Samsung multiroom app driver 4.0 issue

[nrm94ee330]

since updating last week to the 4.0 version from 3.3.8, my Samsung R1 speaker stopped working..
I received many errors, including

Speaker 4.0 groupStop: Not a Grouped speaker.
Speaker 4.0 addToQueue: [status:aborted, reason:Speaker not on LAN]

So I uninstalled and reinstalled the app and ran the app in hubitat

and I had some success ...

Speaker 4.0 sendSyncCmd: [cmd:/UIC?cmd=%3Cname%3EGetFunc%3C/name%3E, host:http://192.168.1.3:55001, method:CurrentFunc, data:wifidlna]
Speaker 4.0 extractData: method = CurrentFunc, data = wifidlna
Speaker 4.0 refreshParse: [isConnected:yes]

but then anytime a "speak" command is given...
I get Speaker 4.0 addToQueue: [status:aborted, reason:Speaker not on LAN]

So I manually copied the v 3.3.8 of driver..
and everything started to work immediately.

I have another hubitat hub that I use for dev purposes..
which is completely clean..
so I installed the whole thing from HPM..
and enabled debug logs..
ran the app and found my speaker and added it..
but if I click speak .. etc it doesnt play/speak.

here are all the logs from the clean install

Trying to troubleshoot..
I commented out the if block under // ========== Play Queue Execution ==========

if (device.currentValue("isConnected") == "yes") {
and the else block.. as well

and now it seems to be working fine...

I also added "device.currentValue" in debugs.. and everytime I get null in that...
and so the "isConnected" == yes block is never executed.

Did you do a save preferences? This will activate the new attribute ("isConnected") which is critical to preventing queue hanging.

Closed due to lack of response for further action.
