Security Token password always invalid now

Ever since the app has been updated today (20/Dec/16), any one-time password I use from it to login is being rejected by the launcher. I tried about 7 times and got my account locked down because of it.

Is anyone else having this problem? I'd hate to remove the token from my account just to have it stolen, all because of some bug.

Check your time and date are correct and accurate (including timezone). Also within the app (on Android at least) you can go into the options and synchronise with the server so recommend trying that too.
