Insync as Flatpak (Linux)

Hello everyone.
There might be some error in the translation as I don’t speak English and I’m using a translator.

I would like to know the development status of Insync on Flatpak. I am a premium user and constantly have problems with versions that do not work in the distro. Especially when a new version of the system is released.
I am currently on RHEL 9 and insync simply does not work. Even following this step by step. For RHEL 8. the application installs no longer opens at all.
So my question arises about the situation of a Flatpak package because then we would have all these problems solved. Since we pay for the application and use another app that works in its place to have access to its features is irrational.

I’m waiting for your positioning.
Att.
