Ashutosh Tripathi Greetings & Welcome to Microsoft Q&A forum!
I have created a Azure AI hub and a project inside it. Why can't I upload multiple files while adding my own data?
For clarity, please provide more details for further help. Are you seeing any error while uploading files?
Can you share screenshot? Are you referring to Playground or Data Section?
I see both have an option to upload multiple files.
Do let me know if I'm missing something here so that I can help accordingly.
