Sometimes I'll be mentioned and I don't get a notification and then I just stumble upon it like 4 hours later. I always feel bad.

Same here, it’s due to Warpcast. Supercast does not have this problem.

I’d have one alternate client at least. joined their telegram and the dev says they’re working on iOS app. For now it’s web only ux wise it’s not worse than Warpcast.

However I find the notification feature to be better on supercast

Did you get supercast Michael? I have been debating it, but haven't yet
