Language progress being stuck for 10 minutes

So, I’ve updated a file with a huge new version. It’s an Excel file, so there’s also some languages, it’s a multi language Excel.

It was about 10-15 minutes ago, so I see new record in revision history of the file, but i don’t see any change in progress language bars and no record in activity. Is this a bug?

It has a delay if the file is really, really big. May take up to 6-7 hours to display the progress and record in activity if the update brings let’s say 1 billion new strings.

But usually, with just a huge or big files, it takes not more than hour. Sometimes hour and half.
