After iOS 16.3, notifications show up, but don't make a sound on the lock screen.

This morning I updated my iPhone 14 Pro to iOS 16.3, and ever since then any notifications I receive on the Lock Screen don't make any sound. I still receive the notifications (iMessage, Mail, Spotify, YouTube, etc.), but they just sit there quietly. This issue was not at all present yesterday before I updated the software, nor have any of my settings been changed. I think this is a bug that comes with the update.

What I've already tried (to no avail):

• Restarted my iPhone
• Checked that no apps had 'Deliver Quietly' turned on, and they don't
• Checked my sound settings; all on max volume
• Checked if I was on 'Focus' mode, I'm not
• Tried replying through MacBook, no change

If no solution pops up here, I'll try contacting support in the following days. I think this is a pretty big issue. I've already missed a few crucial notifications.
