I recall that just before last Christmas (2021) some users reported here that the x64 windows defs and client install files had vanished from SEPM. Well, it's just happen to our site as well. Mac, Linux & x32 remain but x64 has vanished. If I add it back, it 'takes' and I get a confirming email, but 3 or so minutes later it has vanished.
I've opened a case with support but whilst they agree it's a known issue they don't have a solution as yet.
Anyone else seen this & got a fix?
Thanks.
