Good evening

 

I created a quiz in SLIDO. When trying to join by scanning the QR code or submitting the code, we get this error (for multiple people en multiple devices - phone & laptop).

 

“TypeError: Cannot read properties of undefined (reading 'length')” 

 

How can we solve this? We need to use it tomorrow morning.

 

Thanks!

 

Kind regards,

Kaat

Hi ​@Kaat Quintens!

I would reach out to support@slido.com.  If you can provide the slido code and name associated with the PowerPoint, they can help troubleshoot this for you!
