Cam2 Slow live view & playback on iOS

After the last 2 (I think) updates on my iPad the live video and playback of recordings is like it’s in slow motion / glitchy. Possibly since 16/06. Viewing on my android phone is fine, so to me it’s something to do with the iOS app/last few updates. Has anyone else experienced this slow video footage on iOS?

I hope this isn’t due to my ageing iPad (gen 3 retina) but here’s some version info.

IPad iOS 10.3.3 14G60 (I cannot update to a newer version)
Eufy app v1.9.0_567

Any help appreciated,
Thanks, Matt
