Customer has upgraded from 2018 R3 to 2021 R2. A lot of his custom reports now don't show up in the reports menu. I ran a metadata refresh and one of the missing reports did then show up, but not the rest of them.
The reports are all still in the Custom_Reports table and the Custom_ReportBands and Custom_ReportFields records seem to be intact.
I've run out of ideas - does anyone have any pointers as to where I should look to debug this issue?
Thanks
