Pardon if this is already discussed. Does the electronic key on cell phone roll-out seem challenging. Multiple keys need sent to phone, Keys not working, adding night throws key off, Keys stop working mid-stay, Front desk has not figured out how to distribute paper documents, meal certs, bar discounts etc with electronic key. I have found issues with low end to high end properties across the system. Front desk personell not trained or have not seen key functionality. Call number given when key does not work, and operator (usually now off site) does not know how to handle etc. Even the give us comments link on the key does not work on phone app.
