I have the very same issues. I’d like to switch to vscode and everything works perfectly, except that there are no auto suggestions at all. I can hover over functions and classes and get all the info I need, can jump into their declarations and definitions etc., but neither starting to type the name of a function nor hitting ctrl+space displays me any auto suggestions. It just either displays a list of words used in the current file, or says “No suggestions”. I guess there is no solution for this yet?
