We recommend users have a minimum of 1 GB of storage to avoid glitches and errors in the customize layout or recording phase. If you are experiencing issues, try freeing up some space on your phone by deleting apps or photos you don't use anymore.
For iOS users: You can check how much storage you have available by going into your phone Settings, clicking the "General" tab and then clicking "Storage & iCloud Usage." If you click "Manage Storage" you can see a list showing how much storage each app is using, which can help you decide where removal or cleanup can free up space.
Another cause of the glitches could be internet connection. Please check that you have a strong signal and sometimes switching between wifi and cellular data can help.
