Ring Stick Up Cam wired and Virgin Media

Having just moved from Talk Talk to Virgin Media, my Ring Stick Up Cam is now freezing in the first 10 seconds of every recording. It records about 1 or 2 frames of footage in this time, then begins to record properly. The camera worked fine every time on Talk Talk (except for the global issues last week with missing videos). The new connection is 100MB and the old connection was 35MB, so is now almost 3 times faster. Any other UK customers have problems with Virgin Media fibre and Ring cams doing this? Thanks Andy
