Goal: Save translations to Cloud TM by interactive commit in Online Editor.

I confirmed that the Cloud TM is set up to be used for the cloud project. Lookup, concordance, and update boxes are all checked.

When I commit the segment in Online Editor, go to another segment, and go back to the first segment, I expect the translation I committed would appear in the Lookup pane, but it does not.
I went through Translation Memory Update step in Workflow. My translation is still not saved in the cloud TM.
If I use Trados Studio for the same cloud project, my translation is saved to the cloud TM when I commit segments by Ctrl + Enter.

How can I save my translation to the cloud TM while I commit segments interactively in Online Editor?
