General Object Cache problem

Dear Support,

as soon as i enable an object cache, let it be redis-object cache or the APC object cache, the sitemap does not update any more until i clear the object cache.
Probably an object (object group?) needs to be cleared or even not cached at all.
My i ask, which object i have to skip/clear in object-caching, to skip/clear the object cache for the yoast sitemap(s) on a site update or new post?

Kind regards,
Markus
