❓ Question

When I acknowledge a notification on the web interface, it is not acknowledged on the Android app (and vice-versa). Is this normal and expected?

If this is not normal (= one ack should do it for all devices) → is there a specific thing that needs to be open between the devices (I do not think so, I am asking just in case -- they all ultimately point to the same instance)
If this is normal → I will raise a feature idea :)

This is the expected behavior right now. There have been discussions about implementing sync across devices, but it hasn't been implemented yet (and there's no estimated timeline)

Thank you for the answer. I infer that since the acknowledgment is purely local, ntfy is a kind of subpub system without centralized message handling, right? (as opposed to having the clients poll a centralized DB and push their acknowledgments there)

This is purely an "out of curiosity" question.

Haha, yes, "ntfy (pronounced notify) is a simple HTTP-based pub-sub notification service" (from the first line of the website)

Right now, subscribed topics can be synced across instances of the web app (so if you subscribe to a topic on your desktop in the web app, the web app on your laptop will also subscribe to that topic). That is done using a special "sync" topic in the background. I presume message syncing will work similarly

I should be more careful reading the web site (I jumped to the docs :))

Thanks a lot - it's all clear now!
