Because Zorin 16 uses GNOME desktop whereas Zorin 15 uses either XFCE or GNOME. Different desktop may require different solutions.
Yeah, my entire desktop environment is gnome, the only thing I've changed in that regard is the default file manager ( Nautilus to thunar)
would need to be =9 on Zorin 15. I was just checking if that was the trouble (it's not, since you are on 16).
I still think it is much easier to install Flatpak version from Software, unless there is absolute necessity to avoid Flatpak.
I agree with @FrenchPress. I actually like Flatpak and Snap even though most others hate it....I know most snap apps are buggy and laggy but I usually use .deb or apt to download those particular packages. All others are flatpak. I don't use any snap packages right now (I used WPS Office and Bluej previously). As far as storage is concerned I have lots of them, so I don't really have any issue with it.
A contradiction, here...
Yep, I clearly made a mistake there. Edited it now....I liked the snap version of WPS office which was very smooth and faster as compared to the .deb package. I also tried Bluej (the snap version) to get rid of a bug but the bug existed in the snap version as well. Look here:
