Revoking access to shared item from the laptop browser and through iOS mobile app does not work. Access revocation notification appears and immediately shows up in the shared list.
I'm experiencing this, too. On multiple windows browsers and on my iOS device, when I revoke access to an item it says that it worked, but the person's email / name do not disappear. I've tried refreshing my cache, closing my browser and reopening it, and logging out of LastPass and back in. None seem to help and I still have shared access with this person I no longer want to have access to my items.
