The weights in their filters are crowd-sourced, so the best thing you can do is mark them as not suspicious (if you are certain, of course).
FWIW, I am not seeing this. My Spam label contains just spam.
Finally, it would be good to know what you are observing. Are you seeing this as recipient or sender?
As a recipient.
- Emails are being aggressively marked as “suspicious” out of the blue (USPS, HR emails, system emails, promotional emails)
- Those emails are being regularly delayed by 7-10 minutes.
- Priority inbox rules seem reset
- “Never mark as spam” rules are seemingly not respected
