Type Error when trying to access SLIDO in PPT

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 our support team directly to help with this.  If you can provide the slido code and name associated with the PowerPoint, they can help troubleshoot this for you!
