Hey there! It sounds like the issue might be with your browser or the website itself. I’ve had similar issues in the past. First, try clearing your cache and cookies, or use a different browser to see if the upload button works. Also, make sure the document you're uploading meets the size and format requirements.

If none of that works, you might want to reach out to customer support directly, they should be able to check if there’s a technical issue on their side.

That may not even be the cause @kori. File uploads are not allowed on the mobile app. Login via browser to do so if you've been attempting to upload a file from the app

I had the same problem when I tried uploading my document last month. Clearing the cache did the trick for me. Give it a try
