Have you checked your Munzee account details lately?
We want to make sure you don’t lose access to your Munzee account! A future update will require you to use your e-mail address instead of your username to log in. This also means that any Munzee accounts sharing an e-mail address must be updated so that they have unique e-mail addresses.
Please do take some time to make sure your e-mail address is correct. You can do so at https://www.munzee.com/settings. Make sure to click the green [Save Settings] button if you make any changes!
