Hi cansteg,
New tags that you create on the iPhone app should be synced to the web app. Would you be able to contact us so we can get some additional details on this?

Thanks!

I have the same problem!

Hi maybe__yes,
Would you be able to contact us via email as well so that we can take a closer look?

Thanks!

I'm having the same problem on Android. Have you made any progress on it yet?

Ah, wait a minute, I might have a clue. The Android app lets me create a tag with no assigned tasks, but those are the ones it won't sync. If there's a task associated with it, it'll sync it.

kcshrader,
That's correct; tags created on the device will not sync unless there are tasks associated with them. The same happens when there are no longer tasks associated with the same tag; it will remain on the device but will be hidden from the web app.

Hope that helps!
