Mobile usability issue

I'm talking about the Mobile friendly test.

I see. Sometimes, one factor to Google not loading all resources of your site, and correspondingly resulting in a failed mobile friendly test is the business of the servers.

To reiterate, sometimes, their servers are too busy that it fails to load all resources of your site. If so, the result of the mobile friendly test would be a false failed test.

I think the server is fine. I have distributed server availability resources efficiently.
My site is very fast when the ads are removed. I don't think it's a server issue.

Oh, I'm referring to Google's servers. If your site sometimes passes and sometimes fails, It may be a false failed result because Google servers are too busy at the moment. It's advisable to re-try testing at a different time.

Thank you for your support.

I think the same. Recently, I've seen data that seems to have drastically reduced crawling resources.

I will try some tests first and share them.

After a few days of testing, I decided it wasn't a CSS problem.

If there is a CSS ISSUE that I am not aware of, please share.

You're welcome Lee! Hope your tests go well!
