We initially purchased Evernote premium last year on one of our evernote accounts and it worked fine and was able to share all subscription benefits with the other users that i was shared with. This year i have gone to renew the subscription but have accidentally purchased it on the other account and not the same account that it was purchased on last year. The other user (who purchased it last year) is now unable to access evernote and is asking that they update their subscription even know i have done this on my account. Could anybody please shed some light on how i can pass the subscriptions benefits which i have purchased onto the shared users on my account? Thanks
