You might have turned on “CAO mode” (Commercial Airline Overlay charts) in which case charts specifically optimised and created for commercial airliners show Cat C/D minima only.
You will then also find this symbol at the top of the chart page:

Usually it’s because of the small prints in alternative inbound or missed procedures, Jepps tend to put their legs in “busy pilots shoes” (sometimes AIP plates with well funded NAA will abuse this by adding load of Z, Y, X…or CatA/B plate), I just checked, it’s here:

I’ve always checked the Navigraph plates with the Notams and, if in doubt, I’ve used the AIP National plates – although for clarity and consistency I have always preferred Jeppesen.

In this case the AIP chart won’t be updated either — you have to use the NOTAM. As wbardorf wrote, Jepp sometimes update their charts ahead of the AIP updates when there is a permanent (or long-term) NOTAM.

Apparently not necessarily in that order looking at EGTK. The UK AIP is updating the chart only with the 29 Dec 22 AIRAC cycle: https://www.aurora.nats.co.uk/htmlAIP/Publications/2022-12-29-AIRAC/graphics/321739.pdf
I have found that Jeppesen do their best effort to incorporate NOTAMs for permanent changes affecting an instrument procedure but have found that inconsistent. In one case a few years I e-mailed Jeppesen regarding a relatively old permanent NOTAM and they then updated the chart.
So keeping this on topic… Navigraph might show stuff a bit later than Jepp.
Minima changes are unlikely to be really important
Usually yes: notams from no LPV, no ATC…rarely change the physical world, so irrelevant 
OCH change with new erected obstacle notams on 200ft DH ILS, well not sure?
Notams are always #1.
AIP next (the legal backstop, although we know it doesn’t work that way in a lot of places)
Jepp next.
Minima changes are unlikely to be really important.
