I earned a score of 1017 which, at the time of writing, would have placed me into the top 10 and complete the relevant achievement. However, when I clicked "collect points?" I'm told that this score has already been submitted. Checking my high score list, this is clearly not the case as my personal high score has not update from 753, and clicking the submit button again (as suggested by the error message) doesn't change anything. It continues to give the same "score already submitted" message.

This issue occurred around 15:10 PST on 10 August. I'm accessing the site via Chrome version 84.0.4147.105 on Windows 10 version 2004 OS build 19041.388. I had recently received the connection issue pop-up a few games prior.
