Application from flathub can not be installed on Debian Buster (arm64) but works on Debian Bullseye

I try to install Thymio Suite on raspberry pi using 64 bit raspios, based on Debian.
In the passt the installation always worked, but since a few weeks, it does not. No I see, it installs on another raspberry with newer version of Rasspios based on Debian bullseye. I use the same script to install the flatpak on with raspberry pis.

on the one with Debian buster I get
Nothing matches org.mobsya.ThymioSuite in remote flathub

on the other it just worked.

Please install flatpak from backports. Due to internal ostree limit, we had to move arm64 to “subsummary”, which requires relatively recent flatpak version to work.
