Hi @sehlisehli60,

Have you made sure that you’re preloading all of your resources appropriately before initializing any meetings? Note that some of these errors are just warnings and may not affect your implementation directly.

You can also test with our other sample app to see if an issue is related to your implementation or the functionality of the Web SDK.

Thanks,
Will

Greetings ,

I thank you so much for your help sir !

No problem, glad I could help!
