As part of Crunchyroll's unification of fan services announced in March 2022, the Funimation app and website will sunset on April 2, 2024.
That's the end, even without all of Funi's exclusive titles being moved to CR.
One of the side effects is that all your Funi-bought digital copies are gonna go poof on April 2 because CR doesn't support digital copies. Lots of other info in the article.
