@matram I’m not sure about the old hardware. Perhaps it’s the architecture? There’s a reason why Run got totally new firmware (v3) that’s incompatible with the current (v2). It’s still a mystery to me why I can run Constantin on my old S9PP (the first device with UI2) with navigation and notifications along ZoneSense or other heavy apps, and it doesn’t crash, but it does on Vertical 2.
