Hi @vincentditlevinz Welcome tho the community and glad you got your issues resolved.
I think there is a bit of confusion.
This forum / community does not deal with AWS Managed Opensearch service we support the official Distributions of Elasticsearch and Elastic Cloud .. The Official Elasticsearch Hosted Service.
The AWS Managed Service is a based on a past fork of the Elasticsearch code and thus is very different that the official distribution and hosted service.
If you want the best Product and Service perhaps you should try the official Services

And here is a little bit of the difference between our Official Offering and AWS Opensearch.
