My widget stopped working after an update

This is a known iOS behavior: after an app updates, its widget can fail to load until the device is restarted.

Restart your iPhone or iPad and the widget loads again.

If it still looks wrong, check these two things:

• Which list the widget shows. Each widget carries its own configuration, so the list is set on the widget itself. Touch and hold the widget, choose Edit Widget, and pick the list you want. There is no widget list setting inside 2Do.
• Whether a passcode is hiding your tasks. Tasks from password-protected lists never appear in a widget, and with Lock everything on, widgets show tasks only while Allow Widget access when protected is on. Both are in Settings > Security.

See Widgets for the full widget set and its options.
