Datagrip issues for Oracle 19c database

I've used Datagrip for a while with both SQL Server and MySql, but the experience with Oracle has been very different so far. I'm having issues with a lot of basic features I took for granted with the other databases I've worked with. There is little information about these issues in the Datagrip documentation and it's hard to believe that this tool is so lacking for Oracle. Typical issues: - Struggling to synchronize with incoming updates to schema and similar changes(might be performance related) - Types, columns, tables, etc. aren't being resolved - There are user schema's with connections(e.g triggers) to other tables not owned by itself which I can't see anywhere in Datagrip. Any input on resources or solutions are much appreciated!
