Maybe the public can be divided into subgroups with different needs. Ubuntu Touch has to fulfill those needs.
Newbies that are not so into terminal coding generally say Ubuntu Touch is buggy. That the text is so small overall. That the text cannot be easily adjusted. They cannot see the text! Major road block for some.
The cookie nagging in Morph browser can drive somebody nuts, especially if they can't figure out how to block those cookie questions. Adblock exists in Openstore, but there may be difficulty to find a cookie question block solution. Or youtube ad blocking.
Some newbies want a laptop Ubuntu Touch like a Xubuntu desktop. Few understand that literally means to work inside a Libertine container with a terminal, inside Ubuntu Touch, but still isolated from Ubuntu Touch. That they need a device with USB3, external monitor and desktop mode to get things done. Or with snaps. It is not easy to grasp how Ubuntu Touch really works inside as a newbie. Major road block.
Offline GPS navigation with route planning is definitely on many newbies wishlist. If this part is too buggy it cools down emotions. Music player is there thankfully.
Signal is probably one such app that has to exist on Ubuntu Touch natively and work well. There is no way around it. Communication is high priority for some and a show stopper for many if not available.
Comparison: zoom does not exist for linux aarch64. Games do not focus on snapdragon chips. Result: people regret buying an arm computer because their wanted apps are not there. Same with linux distros lacking those apps people want.
Others want EPUB3 in night mode with proper fonts and good rendering. Try to find any android app that can render epub3 with inline svg graphics as well as those two most used apps in Openstore. Here is the uniqueness in Ubuntu Touch. Still, the epub3 viewers have some noticeable bugs which cools emotions. Night mode flickering between pagination is one.
What is downloaded most usually is most wanted by many. Many times it is games. The core apps are expected to be there but maybe do not get as much attention. Gameboy emulator is really good! No bugs there.
Lets look at the app ISODrive. It really solves a big support issue. But it does not work in 24.04/daily. Creating a bootable USB-stick when your laptop needs reinstalling is a nightmare when you are travelling, right? Here you have a unique thing, but it is not working. Why not fix it? Such things make effect because they are needed and solve a real problem that arises quite frequently.
