Approximately 50% of the time, I am unable to backspace (to fix a typing error) when using the add-in.
we are aware of this issue and will address it in the future release of the Todoist for Outlook plugin. We're sorry for any inconvenience this issue has caused you.
It seems that the main reason for this problem is that after opening a task input field, the focus isn't set within this field so for no, please try to click within the input field after you enter edit mode.
Another cause could be the resize of the Todoist pane after which this issue may occur in the Quick Add feature.
clicking in the box before typing does not help, unfortunately. Also, when adding the task, the pop up box is really wide, and is UNDER my outlook, so I have to resize the side panel to about half the screen to see what I am typing.
indeed, after resizing the pane, this issue persists even in the regular input box. We're sorry for the inconvenience and will address this issue in future revisions of the plugin.
For now, you could try to drag the pane out of its fixed position by grabbing it at the top and pull it out. It seems that in the non-fixed position, this issue should not occur (even after resizing).
