Seems to be two issues; does the lever stick when you are trying to change with a thumb push down?
Assuming the cable tension is correct, a shifter spring upgrade solves most things..
Got a load due early next week

It's exactly as the the guy demos in the Malaysian video, the lever reaches the end of the range of motion before it can shift gear. You need to press it further than the range of motion to shift gear.
I got a new cable tension adjuster and installed it for her which allowed me to set the tension correctly (according to the brompton video), but the issue is the same.
Does the spring upgrade reduce the range of motion needed? That would work.

Friend of mine has an issue where the new style 3 speed shifter doesn't shift to lower gears unless you over extend the lever.
Other forums and YT videos say this is a design flaw whereby the shifter expands at hot temperatures, like direct sunlight, and is fixed by filling down and/or sanding parts inside the shifter.
Is this correct?
