2022 Critical Power Graph issue after update

Continuing the discussion from Zwift power curve is bad:

The Critical Power Graph is broken again for me after it was fixed around 18 months ago. I have what I believe is very old data back in my graph. Years ago I started Zwift on rollers with zPower. This was not accurate as I could maintain the maximum 400W with a high cadence. It was garbage data and I couldn’t up the resistance.

I bought a smart trainer and deleted my old data that had a flat horizontal section on the power curve at 400W.

Now my old data seems to have returned and the power curve is useless unless I delete all my years of Zwift power.

Anyone else suffering from the little issue?

After the update I cannot delete my old critical power curve. The old data is useless due to subsequent medical problems.

If you have both tried resetting the data per Zwift’s guide then it’s very like the same cause as @oldnapalm discovered/mentioned in this thread …
