Loved immich over that last year or so but at some point in the last couple months (not sure on exact timescales) the iOS app can upload photos to the server, but can’t actually load them for display. The “missing” photos still appear on the web app.
After a little bit of research I reckon my issue relates to this GitHub issue and incorrect non compliant modified dates albeit not certain.
I have also posted in the GitHub issue but posting here to see if anyone can help fix.
