Wattbike Atom - latest firmware update

Hi mate thanks for the advice but I think I’ll have to show a friend the reply as I am not too good with technical side of things .
Basically I done a warm up on the wattbike app, perfect . Did ramp test on trainer road app, didn’t notice anything.
The next day I did the first ride of the plan which was taku, if your not familiar with that it’s a 30min steady ride… the power kept firing up and my cadence would drop to 50 rpm Even though I was riding steadily , It was so frustrating !
I’ve got a screen shot of the ride to show how unsteady my power was


Last night I didn’t want to take the chance so I jumped back on my tacx flux . Absolutely no problem atall
I use an iPad for the workouts , do you think I should try using my Mac book aswel to see if that helps?
Thanks .
