SUMMARY
SMS messages are sent but not acknowledged and replies are not received on Pixel 4a5g running CalyxOS 4.7.5.


STEPS TO REPRODUCE
1. Pair phone with computer.
2. Send an SMS to a contact from the computer.

OBSERVED RESULT
Messages are sent to contact but the message appears gray (unacknowledged?) in desktop UI and replies from the contact are only received on the phone and not the computer.

EXPECTED RESULT
Sent messages should turn black and replies from contact should be received (tested and works on Pixel 6 running stock Android).

SOFTWARE/OS VERSIONS
Desktop OS: PopOS 22.04
Mobile OS: CalyxOS 4.7.5
Android KDE Connect 1.23.2

ADDITIONAL INFORMATION
Several warnings are posted in the attached Android logs, but I'm unsure which warning is the primary issue or what configuration the CalyxOS system may be missing to support the SMS message acknowledgement and receiving functions.

Some of the suspect warnings and logs include:
* W ContextImpl: Calling a method in the system process without a qualified user: android.app.ContextImpl.sendBroadcastMultiplePermissions:1222 com.android.server.TelephonyRegistry.broadcastServiceStateChanged:3085 com.android.server.TelephonyRegistry.notifyServiceStateForPhoneId:1616 com.android.internal.telephony.ITelephonyRegistry$Stub.onTransact:492 android.os.Binder.execTransactInternal:1285
