I turned off lockdown mode and I still can’t read a previous message

Hey there, kedrin225,

Thanks so much for using Apple Support Communities.

Lockdown Mode shouldn't prevent you from viewing your messages. When it comes to Messages, "Most message attachment types are blocked, other than certain images, video, and audio. Some features, such as links and link previews, are unavailable." However, "plain text messages continue to work while Lockdown Mode is enabled". This information can be found here as well: About Lockdown Mode - Apple Support

If you share some additional information about what you're experiencing exactly, the community may be able to be more helpful in future replies.

We hope that this information is helpful.

​Have a great day!

I turned off lockdown mode but still can’t open video attachment

payment was sent through text message as an attachment while in lockdown mode. The link said “this cannot be opened in lockdown mode.” I turned off lockdown mode and the attachment continues to say “this attachment cannot be opened in lockdown mode.” Lockdown mode is off

I'm having the exact same problem: I've turned off Lockdown Mode but a couple address cards that had been texted to me still aren't openable despite having turned that mode off. I get the same "Cannot open Message in Lockdown Mode" error on my screen even though it's off.
