Having encountered the crash with this version, I took the usual step of clearing data and attempting to set up the app from scratch. While the fresh install does not crash, it does not allow syncing more than vault via folder (I have not tried other sync styles).
I have multiple vaults, one for personal, one for work, etc. Each vault has a separate folder sync location on Android. This has worked with previous builds.
In this build I can create a new vault "Personal" with the same vault password that I use for the synced vault on other platforms. I do not store the vault password in the primary vault (this was not required previously). If I configure this vault to sync, it works fine and the empty vault is populated with sync information from the folder as expected. Multiple syncs can occur without issue.
Then I add a second vault ("Work") with its own (different) password and set it to sync with a different folder. This also works, populates the new vault with the appropriate information, etc.
However, as soon as I add the Work vault sync, the Personal vault sync begins to fail and reports the wrong password. Entering the correct password for that vault does not allow it to sync (reports incorrect password). If I disable sync for Personal, and then reenable it with the correct password, it begins to sync again, but immediately breaks the Work sync in the same way.
This pattern repearts for vault 3, 4, etc. At any time only the most recently configured vault for syncing works, all the others reports they have the wrong password, even though they were able to sync before. Its almost like Enpass has forgotten that each synced vault can have its own password.
