M Performance Drive Analyser issues

[pmilani]

Hello, I have a M Performance Drive Analyser, using it on iPhone XS.
I recorded a few sessions on the race track including video. All sessions exhibit a very noticeable delay for data rendered in the overlays.
Anyone has such issues?

Previously I have used M Laptimer which worked decently, but I have no camera so I switched to M Performance Drive Analyser.
Another thing I don't understand: M Laptimer seems quite fluid on data playback, unlike an always jittery experience with data gauges in M Performance Drive Analyser.
Also, having paid for M Performance Drive Analyser, I expected better features.
Why does it not record the brake pressure and show a graph, only on/off?!? Laptimer does the graph.
