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.

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

Not sure if that worked for you but it did not work for me or a few other users I've discussed this with. The drives still do not auto-mount at start.

Ah, I see. It's worse than I thought. I hope Apple gets on this ASAP. I've reported it via Apple Feedback.

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.
