Feedback On New 2021 Google update effect on Rankmaths?

Just feedback, i use Google instant index beta plugin, and i follow Rankmath’s all content optimization guidelines as we write blog posts and then i published,

After new Google update July for spam link update and indexing i noticed some of my indexed posts disappear after few days, then resubmit it and indexed again and in few days it disappears again, then i removed Beta google instant index plugin and i convert all dofollow external links to nofollow and published again…and few days go by post indexed, and now it is there all the time…

so my take: 1. maybe you guys have to reconsider new content optimization tricks,, sicne google new update i read, they like all external links to be nofollow… something like that.. May be i’m wrong but they want all sponsors links and affiliate link mark as sponsor links so it’s time to reconsider those guidelines for rank math optimization..

2. please double-check if google get pissed off if we using instant index api plugin.. or something they don’t like…. it make indexing because it works… but then when new algorithms kicks in it remove those instant indexed URLs from search results.. Something is happening like that.. you are the experts so please see if there is any fix need to be done… thanks…
