Haven't used Dropbox for a while. No problem signing into my account on dropbox.com. No problem re-installing on my Mac and managing files from there. I removed about a dozen old linked devices, keeping my main computer because of the free account rules, leaving just the main computer linked.
- Attempted to sign in on an iPhone XR not previously used with DropBox.
- Checked app was properly updated to latest release available for iPhone XR.
- Tried three times to log in. Each time, I was sent a one-time security code by mail, which I entered.
- The app would not allow me to sign in on the iPhone with the security code. I did carefully check each time that the security code matched the email. (Plus Apple provides auto-fill, detecting the code from email, and they matched. Tried once with auto-fill, twice with hand-entry.)
- After the third attempt, all logins on the iPhone XR now say "The provided user information isn't valid". I don't even get to the 2FA/security code email step.
- Web: No problems.
- Mac: No problems.
I was planning on using DropBox to store presenter notes for a trip in about a week.
Help appreciated. Thank you in advance.
