@Danp I was going to do the upgrade over the December / January Christmas break in Australia but that is when this issue became apparent so we didn't want to be making major changes until it was resolved.
I note @anthoineb noted the first report was late August / September 2025 which was just before 8.2.1 reached EOL, so it would be a shame not to have a fix for it tested on 8.2.1 as it seems an upgrade to 8.3 would be unwise while we still have this issue?
