Nope. looks to me as ifyou were right first time...It's gone into one of the previously aforementioned gaps in coverage somebody was boring on about 🤐
Track went predictive a while back, (not logged on via satellite.)
If you looked at the Data source info for the flight at that point it stated:
"Data source - US/Canada radar
3rd party data covering North America and certain oceanic regions around North America, aggregated from different data sources. Provided to Flightradar24 as is with variable quality based on multiple factors."
i.e. "there's not a lot/any coverage and any that is is poor"....now FR has dumped the flight..
It'll probably reappear off either southern Greenland if it tracks close enough or when it approaches the Canadian coast.
