Hm curious... this does not fail on my local machine.. Will investigate

[nikosbosse]

still confused.. @Bisaloo do you maybe have an idea? It seems like the snapshot review fails, but there is nothing that I can update on my local machine. Potentially related to: r-lib/vdiffr#117

I can look at this later but we have a solution for the original problem in EpiNow2 I think

[seabbs]

As a test does the vdiffr issue happen for any PR or just this one?

apparently this was due to an outdated version of an upstream package on my machine. Updated, recreated the plots, updated the snapshots and now works like a charm
