The problem here is the same presented by Dogor in 2018: Platform low Max Speed count as “Not moving” - GDevelop general / Bugs reports - GDevelop Forum (gdevelop-app.com)
In 2020 another post was made in bug report: Platform object simulating LEFT/RIGHT key not firing moving - GDevelop general / Bugs reports - GDevelop Forum (gdevelop-app.com)
Gruk suggested: “The only ways to solve it is to increase the speed of the object (or time scale), or to add a feature request on the forum about this limitation.”
I didn’t find the request, so here is. The request to finish with the limitation of Gdevelop counting a “not moving” the moviments with max speed below 60.
