Hi alicea,
Can you describe what you're doing specifically? Are you viewing a particular search/List/Smart List? Does this happen with just this one task? (If so, can you describe some of the other available fields for it, e.g. due date/repeat/list/etc.?) When you press Enter after adding the tag, what happens specifically? Do you see the spinner on the right side of the task and/or the status bar at the top saying what was just applied?

Sorry for so many questions, but we'll figure it out!

I am in a specific list, I have this one task I noticed does not have a tag (I tag every task). The only characteristics of the task is that it repeats monthly.

I select the task (shows checkmark), I click on the icon for tag which is "none", I enter the tag and hit enter twice (once enters a comma for the next tag and enter completes the entry).

Everything looks ok but when I navigate away from the task, even if it's just to look at another task, not clicking anything and the specific task still has the checkmark, the tag field is back to "none".

Thanks for the assist. Miky

UPDATE - FIXED (itself)

Out of curiosityI tried a different tag and it took it so I went back and changed it to the tag I wanted to use (one I use all the time) and it stuck.

Go figure. Thanks for the help.

Hm! Sounds like something was off with that task (but it's hard to say what!); glad to hear it's working for you now. :)
