Yep.

it doesn’t save my settings or my favorites and multi-communities.

It should save/persist the favorites to your browser’s local storage. If you’re using a browser that clears site data on close or something, then they’ll reset. But it also wouldn’t persist your profile and you’d have to log in every time, so…🤔 It doesn’t, however, save any settings beyond your device. I’m working on a way to securely save those to whatever Tesseract server you use but don’t have it implemented yet.

This version (1.4.42) also changes where and how the favorites, community groups, and filters are stored in addition to not storing useless data like the community sidebar info, etc. They’re also no longer stored inside your profile in a single local storage object. Since these save to the browser’s local storage, there’s a hard 5 MB limit per object (everything gets written to a JSON string), so maybe your profile exceeded that somehow? If so, there should be browser console logs to that effect. Regardless, this version splits those all up into separate storage objects to address that problem.

Not sure what you mean by multi-communities, though. There was a feature to create custom feeds (which is kind-of similar to multi-community) but I took that out a long time ago because API changes in 0.19.3+ made it untenable. I think that was removed in 1.4.40 or thereabouts, so if you’re on a version older than that, then maybe that feature is still present. That feature was pretty broken for a long time which is why I finally removed it and put it out of its misery.
