At the time of writing (March 2018) we are aware that there are performance issues with the Android apps, and we apologise for any inconvenience. We have made the decision that the apps need to be re-created using different technology in order to make them stable going forward. This is taking longer than we hoped, but we are currently looking at a release during April 2018. We thank you for your patience. 

If you are not satisfied with waiting for this update, please contact customer support and we will do what we can to help. 

Kind regards,

JCM Customer Support.
