After watching Top Gear on BBC1 HD, BBC iPlayer info box appeared "Press red to view all episodes" so decided to bite.
Noticed slight picture error on button press (like turning over a channel on a 70s telly)
iPlayer loaded OK & offered all selections in the splash menu, but when programme selected it got stuck on the buffering circle.
Tried the "backup" remote command & selected a different programme from the Main iPlayer menu & same result.
Then exited iPlayer completely to start from scratch and had the same issue as above.
On exiting iPlayer, Aura threw a bit of a wobbler & all info on live TV linear programming was lost (blank info box in top right hand corner & future guide info was missing).
Info returned seconds later so no real biggie but looked like a bug so reporting here.
(Unit connected by Wi-Fi 5Ghz & updated to latest Beta)
Didn't try rebooting, but I also had similar with ITV Hub last Week where the programme menu was available but when the actual programme was selected, circular buffering then the ITV Hub's "Whoops" notification.
Same unavailability of iPlayer on same session, but powering down & rebooting the unit from active standby seemed to clear it.
