Uploading audio to Cloudinary says "Cannot decode the file"

I’m only getting this error in the Thunkable testing app on my iPhone. In Web live testing all works perfectly fine.

Here are the blocks that give me “Cannot decode the file”:

The “Cannot decode the file” is displayed in Text_Input1’s.

I tried speaking to Cladinary support, they are asking for a file sample. However, there is no way for me to get a file that the Thunkable mobile app tries uploading to Claudinary.

What can I do to make it work?

Hello, please re-upload your blocks image, it seems faulty.
