Incorrect timezone / event time
If you find that event times are different than other members, the time zone in your app may be incorrect. You can change this by going to your profile > "Edit Profile"> "Time Zone" in the app. Look up and choose, for example, "London".
If you log in to the app when you are abroad (in other time zone), the time zone will change automatically. Then you must change as explained above. If you are continuously logged in (which is most common and appropriate), you will only receive a notification that you are in a new time zone.
