I am in the screen logic app on my phone. This is within the speed control portion of the app, not pool or cleaner although they are indirectly affected because the speed set in Pump section tells the pump what speed to run for each of those settings. Here is a screen recording. You can see when I change the speed of the last two, they just revert back and actually change the speed above them. When I change the speed on the Pool setting at the top, it holds, maybe because it doesn't have a setting above it, IDK. Turns out I can't attach a screen recording. but here is a screenshot I have used for many years to change speeds.
Oh, and you can change the speeds with the remote. I believe it is/was called the Mobiletouch. I still have it laying around so I tried that too to no avail.
