I deleted all local files and removed all downloads from iCloud and there is still 1.5 GB of data from SoundLab. What is that data?

This should be an AI Model. Can you use the new version of Mine-> AI Model Storage to try Remove All to clear this 1.5GB data?
That makes sense that it’s the AI model. Thank You!
How do I remove the data from my iPad?

Are you talking about other data?
No you said “This should be an AI Model. Can you use the new version of Mine-> AI Model Storage to try Remove All to clear this 1.5GB data?,, so I’m asking how?

First, please go to Mine → AI Model Storage. At the top, you’ll see “xxx used.” Could you tell me what amount it shows?
If I remember correctly, you’re using an older iPad, so there shouldn’t be many AI models downloaded on it. I suspect the 1.5 GB may actually be project cache data rather than AI models.
I’m currently adding a project cache cleanup feature for the next update. If my guess is correct, that 1.5 GB should appear under project cache in the new version.

Where does it say AI model storage

Sorry, I don’t fully understand what your problem is?
Look at the 2nd comment. You said “This should be an AI Model. Can you use the new version of Mine-> AI Model Storage to try Remove All to clear this 1.5GB data?”. So now I’m asking you, how do I do that? And what should I do?
