OPs issue was more clearly directed at "A week or two ago I was surprised to see a Google Gemini summary at the top of my email on my phone", which Mimestream doesn't include.

The rest of the complaint was about a bug that happened, just today, with sorting and spam control.

The complaint was about the summary, which Mimestream doesn't include.
