Why can't I add sounds

Why can I only add two sounds to the components? Why can’t I add more than two sounds? Do I have to upgrade to a paid version or is something wrong with my devices, because I’ve tried on multiple devices.

You get some notice from Kodular? Some error ? Is a right type of sound ? How big it is ?
If your assets is less then 5mb you don’t need payed version .

It would really help if you provided a screenshot your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.
