Great design, but notifications aren’t working

This is a really great design and I love the customization options.

But, despite all my iOS notifications settings and in-app notifications settings being set to “on,” I’m not getting any notification alerts or notification count bubbles whatsoever.

I’ve seen this be a problem across 3rd Party Mastodon apps, so maybe it’s something to do with the instance I’m in. But, it’s really bizarre, because when I go into Mammoth, it shows that I have unread notifications, but the app isn’t sending me any alerts at all.

This app is simply fantastic!

There are other good Mastodon apps out there but I can honestly say that almost immediately after trying this out, it became my primary client. I have only opened another client twice since, once was to use a feature that Mammoth does not yet have and the other was to compare how something was implemented. That is it, have not really looked back. The app is new but the development team seems really strong & experienced and devoted to what they are doing and to doing it well. Congrats on a job well done and thank you for that!

Almost forgot to add that this app has features I have not found in the other handful of clients I have tried so far. Lots of useful, nifty, extra features sprinkled throughout the app. And it is tiny.

Buggy, but a good start

I've been using this since the betas and it has promise but still has a few major bugs. The first is that a sync takes about 5 seconds on a fast connection. It also sometimes confuses posts and will put the content of one post in another one, attributing the text to someone else's account and avatar. And today I replied with an image upload and the post screen went away as if it was posted but the post disappeared! I posted it again and the same thing happened. I looked through the web interface and the replies just never showed up.
