I'm in need of some help. I'm a bookkeeper new to Dropbox. I had a client send me their 2020 bank statements to me through here since it's more secure that way. When I try to preview on Dropbox I get a blank page with the small words Invalid Application. That's it. I tried downloading it to my own dropbox, to my computer, I tried viewing as PDF. No dice. Please help! I will contact the client and ask her to resend but I want to provide more guidance other than hoping it will work the second time. Thank you!
