Server-side apply for CRD in Helm Chart

[ishaan-mehta]

My Helm Chart has a couple CRDs that are too big to sync client-side. To fix, it recommends user server-side syncing or syncing with replace. Using either of these options works via the UI when syncing the problematic CRDs. However, when I try applying the annotation on the CRDs like so:

metadata:
  annotations:
    argocd.argoproj.io/sync-options: ServerSideApply=true

and I sync (either automatically after deleting the CRD or manually via the UI), it does not server-side apply, and the error comes up again. If I check the SSA box when manually syncing, it works as expected.

What am I missing?
