[Owncloud] older versions of not approved apps

[RoboMod]

Hey List,

today I got a problem with a "not approved" app (roundcube).

After the update to OC 5.0.6 yesterday this app didn't run. This morning I
wanted to "re"-activate it, so I first deactivated. But after that it
wasn't on the list of installable apps. Looking into the app store showed
that it was updated some time ago but not approved yet.

Why couldn't I install an older version?

Best
