Why is the web app more feature rich than the mobile app?
is the mobile app (specifically iPadOS) limited in a way the web app is not? If so how?
Or are the apparent differences just a result of where developers have chosen to focus their resources?
The mobile app is not intended to be a replacement for the desktop app. On the other hand, the web app IS intended to (eventually) be a replacement for users who don't have access to the desktop app. Such uses include:
1. Those who are using linux or a chrome book and can't run the desktop app (windows/Mac).
2. Users, such as students, who need access to their library on a non-personal computer (i.e. at the library).
I really hope they improve the mobile app so that it is almost the same as the web app.
