I have embedded my ZenPlanner schedule into my Wix site and it comes up on desktop view but nothing shows on mobile. Really needing this to work ASAP, any help is appreciated.
If you are having issues with third party code then you are best suited going back to your third party provider, in this case ZenPlanner and asking them how to integrate it properly with Wix. They provide the code so they should be able to provide you with the support for it.

Important:
Wix cannot provide support for external codes that were not created or tested with Wix. If you are experiencing an issue with your code snippet, please contact the provider directly.
