Persistent storage

Hello hoping someone can help me, I run Tails 7.7.3 on my MacBook Pro, and initially when I set up persistent storage worked every time, now it only works 30% of time? Any ideas thanks

It could be worth retesting with Tails 7.11.

I was getting a Persistent Storage error on the welcome view up until 7.11 and now it works for me.

Macs can be pretty picky with USB power states during boot! Are you seeing an explicit error message when it fails, or does the option to unlock persistent storage just not pop up on the Welcome Screen? Knowing if it fails at the LUKS prompt vs. after entering your passphrase will help narrow it down.
