On the installed mobile Apps, when translation strings are missing the default language strings are displayed.
However, with Modern PWA the missing translation strings can cause error messages.
For example the strings for when there are no bookmarks, highlights or notes.
These screens will display: “Undefined”
We plan to add strings for these, but since new strings are always being added it would be very helpful to have default strings displayed in the Modern PWA similar to the Mobile Apps in this situation.
Thank you!
