Now phone calls and SMS syncing are the same setting. However, I would prefer if the settings were separated as I personally want just the SMS syncing for now.
this only halfway solved the problem, while this DOES allow for SMS sync without Call sync, it does NOT allow for vise versa. A request for the latter was placed. https://joaoapps.helprace.com/i577-option-to-disable-sms-sharing-but-keep-call-sharing
