Some churches stream their services at multiple sites.
I checked the St. Andrews Pres FB page, and they post streaming services to their page with a live feed/ability to post comments in real-time.
FWIW, I didn't see NG "liking" or commenting on any of those FB posts streaming the service, so who knows about the report that she only attended virtually.
As others have said, if only the Daily Mail is reporting something, take that something with a grain of salt.
I do have real questions about the timing of the phone call to her family from the church, given that the services are at 9 and 10:45. People would not contact family unless they had tried to reach her first, so LE will no doubt have checked to verify whether that person had tried to call NG first, or who reached out to whom that morning.
That phone call just seemed oddly reminiscent of the Morphew case and "the daughters becoming concerned" and calling the neighbor to go check on Suzanne.
