Hi @Canmer ,
I have had a look online and it seems that others users are experiencing a similar issues with this app on different phones brands. Some of them have reported that selecting the feature that set the time and date automatically on their phones get this sorted. Would you be able to give this a try? This features is available from the phone Settings> General management> Date and time> Automatic date and time> Turn the slider on if off.
