Hi Lisa Price,
Have you had a chance to try the suggestions in the AI Answer yet? If so, please let me know which steps you tried and how it went, including whether anything changed.
To help narrow this down further, could you also confirm your phone model and Android version? Are the missing responses from individual contacts, group conversations or both? When a response is missing from Phone Link, does it still appear correctly in the conversation on your phone?
As an additional check, open Phone Link > Settings > Features > Messages and make sure "Allow this app to show text messages from my phone" is enabled. If the affected messages contain pictures or attachments, please also check that the MMS options are enabled.
You can then try a soft reset by opening Settings > Bluetooth & devices > Mobile devices, turning Phone Link access off and back on and reopening Phone Link.
If the issue continues, please let me know whether it also affects newly started conversations or only existing threads. That should help narrow down the next step.
