No completion in google keep

First of all sorry if this is a duplicate. I did a quick search and couldn’t find anything related.

So when I use google keep to add items to a ToDo list there are no completion suggestions at all.
Similarily in a different matter, when I complete a word but then backspace to change the last few characters the suggestions don’t pick up again.

Finally a question: does smart keyboard keep track of the most common word sequences used to make writing faster? For example suggest the word “morning” when I type “Good m” and used that phrase before?
