Hi Indey and Jason,
In trying to reproduce this, I see that the response from
rtm.tasks.removeTags does include the removed tags. However, for me
it seems the tags are actually removed, as can be seen on the website
and by using rtm.tasks.getList.
Can you both try using rtm.tasks.removeTags, then running
rtm.tasks.getList and let me know what you see for the 'tags' property
on this task?
Regards,
Brendan
