Your instance (lemmy.world) is not using Lemmy 0.19.4 yet

I can do that.

I suppose when muted, posts from lemmy.ml would not appear in my feed. Same thing when blocked. The only difference will be the visibility of lemmy.ml itself, its posts, and communities. If muted, I could still access them, and when blocked, they would not exist for me. Am I right?

Yes!

What about comments and private messages? From my experience, when muted, they are still visible , but when blocked, what happens?

I can only explain the behavior of muting because is the one I developed for Boost. Muting only affects posts in a feed. If you mute an user, you won’t see posts from that user in your feed. It doesn’t affect comments or messages.

Muting is a Boost feature. It won’t show posts from those communities in your feed

Blocking is a Lemmy feature. You won’t see blocked communities or posts from those communities.

Fixed in new beta version 1.0.14

I’ll fix that, thanks for reporting

I’ll add that

By default the app loads low resolution thumbnails when using mobile data, and higher resolution on wifi. To always load high resolution thumbnails, disable data saver options on “Settings-Data and storage”

I am updating the app to support new lemmy features now that I have more time :)

The parameters being used changed with some recent Lemmy version. Fixed for the next version!

Right now I am finishing the “hide post” feature

Boost dev here. There should be an Ad icon on the top right to report the ad. Not sure why it is not showing in this case. I will try to block those ads in the AdMob console. Edit: Done

Added to the to-do list. Thanks
