"Don't show topics from this group" not working

So

Does anyone have this problem; I get topics from all kinds of groups in my community front page. From groups I'm not a member of. And even if I click and choose "Don't show topics from this group", next time I open the app, there they are again. I'm getting a lot of topics there especially from "pregnancy announcements" and that kind of groups, which at the moment is a very touchy subject for me, and that really hurts and triggers me. I'm not a member in these groups, and on the other hand there's no topics on the Community front page from the groups I'm in. I wrote to their support, but in their answer they didn't tell me anything about how to fix this. I'm thinking do I need to find a new app for this.. 🙄
