For a given alert/error message, a version that specified why it was happening and how it can be resolved tested the best on desktop. The current message is 173 characters long (including spaces). But trying to bring that same into the native app version of the website seems too long.
Is there research that compares messages being shown for desktop vs. mobile (specifically native apps)?
There's always a case for consistency but I feel that desktop sometimes allows for a longer message to be displayed without it seeming verbose.
