Sorry if this has been asked/answered already… but can anyone confirm what version of Bluetooth the Sonos Move devices currently use?

I noticed Sonos have updated their “Power + Connectivity” section for the Move, which now states Bluetooth 5.0 https://www.sonos.com/en-gb/shop/move#2

But I’m still seeing messages on this forum, and ‘reviews’ from third party sites as recent as January 2022, stating it still uses Bluetooth 4.2 - has there been a low-key specs update ?
