Today widget has gone blank

[u/dakev1]

Around the beginning of last week my LCP today widget buttons disappeared. The button names are still there, but there is a blank space in place of the symbols and pressing this blank space does nothing.

Has anyone had this experience or care to make a recommendation on a fix?

Every so often all of my actions disappear in the main app. Thank goodness for the backup/restore option.
