How do I disable message sending using the return key on Ipad or Iphone? While using a bluetooth keyboard
By experience, latest macOS (11.1) and iPadOS (14.4) versions let you get a new line by pressing the Shift ⇧ + Enter ⏎
In older versions of iPadOS it would be pressing Option ⌥ + Enter ⏎ (same as for macOS)
