My client's site, which runs on Nuxt and Vue, is not showing meta descriptions on Google SERPs. They used to and as of last week they don't. Any idea why meta description tags would be stripped from the SERPs?
We are dealing with very low performance on page speed so I'm wondering if crawler is fetching code to render and gives up as it is taking too long. If this is the case, I would think Google would show the cached version of the tags until it can retrieve a new one. Has anyone seen this before?
See title tag and description tag missing in SERP. Client name has been changed for confidentiality but all else is the same:

<title>tag, not in a<meta>tag. Furthermore, it is visible to users in the browser window title and tab which makes it not meta from a content display standpoint.
