For anyone interested, RunCam released an update to their SpeedyBee app yesterday (on Android at least) which now supports the new features of Betaflight 4.1. I guess anyone who has automatic app updates switched on will now already have the latest version.

They sent me instructions a few days back but i haven't got around to try it yet. By the sound of it, a pretty cool feature

I just tested it out the updated SpeedyBee app on my quad with Betaflight 4.1 installed and can confirm that all the new features are present including the PID sliders and the new OSD switches that were previously missing when I needed to switch off one of the new warnings in the field last week (HERE) but couldn't because the app hadn't then been updated.

My FC doesn't have bluetooth connectivity so I just use an OTG cable between my mobile phone and the FC which works perfectly

The SpeedyBee app works in exactly the same way as the desktop OS versions in that the GUI and CLI are firmware version sensitive, so depending on what BF firmware you have installed on the connected quad determines what GUI elements get shown and what CLI commands are available.

waiting for IOS to follow...…..should be any day now......
