Sad to hear, just had a look at the readme for that project and it sounds extremely full-featured for a lemmy client.
Hopefully someone can port some of the changes back into Photon, where it originally forked from, or maybe even continue the project, but realistically I feel both of these are unlikely at the moment seeing as very few people have heard of this compared to Voyager (wefwef 😢) and Mlmym
100% this is the best choice for op IMO.
A big pro is that they literally don’t need any Google services whatsoever by the sounds of things
