Often these reports are false positives, i.e. you do not necessarily have to follow them up. They are often caused when the GoogleBot could not load the pages properly. However, it does not hurt to take a look at them.
Regarding point 1: add a logo to solve the message. If you do not want to use a logo, ignore the message.
For the other points you would have to know what the messages refer to. Google even shows a screenshot on the right that was taken by the GoogleBot. Make sure that everything is displayed as you see it in the browser. If the style is missing, then the GoogleBot could not load the style file. This can be a temporary problem of the GoogleBot or also a problem which results from low delivery times of your website. The result of PageSpeed in this regard is quite acceptable: https://pagespeed.web.dev/report?url=https%3A%2F%2Fmycoffeewiki.com%2F – I therefore suspect a problem of the GoogleBot. Just let it reload the page again.

Thanks for replying.
The mobile usability problem is solved after I change from a wordpress free theme to Qi-theme.
But the missing URL still exists.
Please help. Thanks.
