Ranking dropped massively for only one language in the same region.

Hi gurus, my site is targeting 2 language in the same country. The ranking of hreflang-en dropped massively since yesterday. Anyone facing the same issues ?

not exactly, no I did not noticed anything.

What I did noticed is differences beetween mobile and laptop and beetween same keywords in difference countries.

There are strange fluctuations in these past 2 months
