I have had a Dropbox account for years, and I recently downloaded the Dropbox app on my iphone 15, which I got to replace a previous iphone that I damaged beyond the ability to use.
I am logged into Dropbox on my Mac and in my browser.
When I went to log into the Dropbox app on my new phone, I was presented with an interface to create a new account, but not to log in.
I went ahead and entered my email and password for my existing account in that interface, thinking it would provide me with a login interface once it recognized that an account with those credentials already exists. But it doesn't.
So I can't find any way to use this app. What is the solution?
