Time Machine (Encrypted) Not Auto-Mounting on Boot with 10.14.4

Ever since the update to 10.14.4, my external SSD (Journaled, Encrypted) which serves as my Time Machine backup disk does not automatically mount on start-up as it used to.

There are also no prompts for password to mount the disk.

I have to manually mount it each time in Disk Utility.

Anyone else experiencing the same?

PS. I have tried removing and re-selecting the aforementioned external SSD as my Time Machine backup destination.

Issue resolved in Mojave 10.14.5 update today - an OS update via System Preferences/Software Update returned Mojave to its previous and expected behavior of auto-mounting password-saved external encrypted disks on boot/UI login without user intervention.

No issues here. I have an external USB (spinning) drive which is HFS+ formatted and encrypted. The drive auto-mounts and behaves as expected on my iMac running 10.14.4.

My external USB drive is not configured as a Time Machine backup volume. It's just an external disk formatted as "Mac OS Extended (Journaled, Enyrypted)".

No, it's not just specific to encrypted Time Machine-Drives. All Drives that are encrypted are affected, at least on my machine.

Does turning off the encryption mean anyone can do a time machine restore of my files if they got a hold of my drive?

Same problem here, iMac Pro. Initially I was not getting a prompt but now at least getting a prompt with tick to "Save" but sadly it appears each time I restart and Time Machine attempts to run.

Whether or not encryption passphrase is stored in keychain, the encrypted volumes don't even attempt to automount for me.

Sad!
