I did put in another ticket item for this a few months after my previous response and received the same response from Evernote about being "excited" to be able to change currencies mid-subscription, which, again, is not what I was trying to do.
The cost in Taiwan is nearer to that of the price in the US and my differential was based on a huge discount offered to be in one currency but not another. Honestly, I used to think that Evernote was one of the best subscriptions I had and haven't been precisely been able to replicate it but let the subscription end out of principle. In the meantime, it has been blocked on every computer that I use for work out of some kind of security concerns so the decision was a good one and I wouldn't have been using it that much anyway.
I do continue to hope that somebody buys the company and gets things in order.
