I'm sorry you are still having trouble with that.
Have your cleared your cache/cookies recently? That can help with this type issue so please give that a try. Also, you could try using a different browser to see if you get better results then.
If neither of the above work, please let me know which browsers you have tried, plus what version iPad and iPhone you are using. And, do you run into the error when trying to update all of your Other Goals or just certain ones? If you would give me a couple specific examples, it would help us test it out.
Thanks for trying the above and then let me know what happens.
