I second this. Building a Progressive Web App (PWA) will take time and effort, however it allows the team to use one application across all major platforms. The Twitter app is a prime example, just like YouTube Music. It is also a way to bypass app stores and their restrictions to donate a percentage of your income to, for example, Apple and Google.
A PWA can also act as a bridge to have people enjoy Obsidian on their mobile devices on short term, and allow the developers more time to develop a native app in the long term. Flutter is a framework I have read about and seems promising for developing cross-platform mobile apps, including Linux.
Now I am not a developer, so there may be shortcomings that I am not aware of.
