It is important to make sure your MicroBot Hub is updated to the latest version in order to ensure an optimized user experience.
Check whether an update is available. Tap on the MicroBot icon at the top left corner or slide from left to right to access the left-sidebar. In the sidebar, if the orange 'Download' icon appears next to your MicroBot Hub, then an update is available.
Update MicroBot Hub. Tap on the 'Download' icon, select 'Proceed' and wait until the update is completed. You can view the progress of the update (3 steps) in the left-sidebar, below your Hub's name.
