Issue I'm having is my phone does not ring even though I'm listed in a phone group. Everyone else's phone rings but not mine. I'm not too sure on what to do here. Any suggestions?
When you say 'my phone does not ring', you mean your mobile number or the 3CX Mobile App?
If you mean you mobile number, as a first step please check if you have configured a mobile number in your extension and then that the option 'Also ring my mobile' is enabled in the Settings >> Status section of your extension.
In case that you mean the 3CX Mobile App, check for the option 'Accept PUSH notifications' to be enabled in in the Settings >> Status section of your extension.
