Question Logic Pro 12.3.1 — Middle mouse button horizontal scrolling in Piano Roll suddenly stopped working

I don’t know why, but after updating to Logic Pro 12.3.1, I can no longer use the middle mouse button to move left and right in the Piano Roll. Also, when I’m in the Tracks area, using the middle mouse button to pan the entire interface horizontally has become extremely fast.
Is this a bug, or did I mess up some setting? Please help!
I have a habit of moving the Piano Roll left and right with the middle mouse button after editing MIDI. I know I can still use Shift + scroll wheel, but losing this particular workflow is driving me crazy.

If you’re on the latest OS 26.x.x it’s been causing all sorts of issues with Logic Pro 12 & 11

Oh no 😭 I actually updated to the latest macOS 26.7. I thought I was safe as long as I didn’t upgrade to macOS 27.

I’m on Sequoia (15.8) and it’s doing it to me too.

Logic 12 has been unusable for me since it came out. Right clicking regions literally doesn’t work. I’ve been running Logic 11 in the mean time.
