I was initially in serious "like" with Flatpak when I first discovered it, but after using it for a while, I am dissatisfied. For example, I installed PeaZip with Flatpak and added their scipts to my caja/scripts file so they would show up in the context menu... and they did. However, when I tried to use them, they threw an error and said they could not locate PeaZip. I uninstalled it and then installed it manually and everything worked fine.
This is not the first time I have had problems with Flatpak. Sometimes their versions are different. GIMP, for example, I had challenges loading some of the extensions I wanted until I installed it manually.
Anyway, if you do use Flatpak, I would recommend double checking the versions as Flatpak does not always have the latest one and you may not get some of the functionality you were expecting.
