Steps to reproduce
On iPad, press TAB on the on-screen keyboard to indent an item, or Shift + TAB to unindent. The auto-capitalization of the first letter is turned off.
Auto-capitalization stays turned on.
Auto-capitalization turns off.
Dynalist app 1.4.9
I just installed the least version of the Dynalist app which seems to fix the auto-capitalization when pressing Return to add a new item. However, it still seems to turn off when pressing TAB to indent the item.
The same thing may happen with a Bluetooth keyboard, but I don’t have one handy to test it.
