Remember, for the past year or so, there has been a bug where the old Search Analytics report in the old Search Console did not match the new version called the Performance report. Specifically, the report was a day off as we covered here and before. Google's John Mueller said on Twitter. that it was fixed.
And yes, it was fixed. Although there is no way to access those old reports anymore - Google did fix it. I have screen shots of the bug and now it shows the right date.
For example, December 8th was the correct date but the new report showed December 8th data on December 7th. Google fixed it.
Here is what was shown for December 7th before:
Now this is the data shown on December 8th, which matches what the old report showed:
