I recently updated my 1Password vault on Android after being told to do so for several weeks. I've been using my fingerprint (on Samsung Galaxy S7 Edge) to unlock 1Password, and I use my password to unlock my vault on my Macbook. After I updated the vault on Android, my password that I was using to unlock the vault on my Macbook does not work.
Furthermore, when I have subsequently tried to sync my vault on my Macbook to Dropbox, it asks me to locate the vault on Dropbox. When I specify my vault, it asks me to merge the two vaults (since the one on Android is technically newer), but when I'm prompted to enter the vault password for this second vault, it does not work (even though the two should be the same).
1Password Version: 6.8.8
Extension Version: Not Provided
OS Version: OSX 10.12.6, Android 8.0
Sync Type: Dropbox
