how do i clear unread mail in my inbox gmail

I was facing a similar problem too but here was my situation and my fix. What do I do about this? Please do not share a suggestion of something I've already said above that I've done. Only in the banner of my iPhone Mail App. On no other client for my Gmail - not on any browsers, nor on the Gmail app itself - are these non-existent unread emails showing up. I then deleted the Mail App entirely from my phone, went back into the App Store, downloaded it again, re-added all my email accounts, and the '9' banner popped right back in. The '9' popped back up immediately in the banner. I then deleted my Gmail account entirely from the iOS Mail app, then added it back in. I then did the suggested fix on my iPhone by deactivating and then reactivating 'Mail' in the Gmail Mail account setting, didn't work - they came right back, same 9 non-existent unread emails in the banner notification. I looked in EVERY possible folder in my Gmail account on a laptop browser, including the Primary, Social and Promotions tabs, all of the folders in the sidebar tab including the All Mail folder, the Spam folder. This morning, I suddenly have a notification of 9 unread emails on my Gmail account in the iOS Mail app.

I am having this problem that many others have complained about having.
