This really can't be too absolute. I have worked in the company's human resources and received my resume. If there are few applicants, you can try to send more, because on the one hand, you can ensure the success of uploading, on the other hand, you can appropriately leave the image of you as a very serious person to others. But if you are alone, don't send so many at once, because you really don't have time to download and view resumes one by one, then you will only have a bad impression! But generally speaking, if you can't upload it successfully, you can upload more, but not too many, at most 2-3 copies! I hope it works for you! I wish you find a job you like!

Look at how much I type, you have to give me some! !
