Hello!
The title of the topic is self-explanatory: on the latest version of Panels, if you finish a comic, it won’t update the progress widget that one can add to the iOS home-screen and will instead report the progress from the last time the comic was paused.
Relatedly, if a comic is removed from Panels (for example, if you’ve finished it), it may be a good idea to not show that in the progress widget either.
