Autocompletion of session variables and suggestion in vscode-Jupyter

Describe the bug I have run R scripts in vscode-Jupyter for some time. Recently after upgrading the extensions, there is somthing wrong with it. The autocompletion suggestions and the names of variables defined previously disappear in .ipynb files even though the appropriate IRkernel have been installed in Jupyter. But it still works well in .R files.

To Reproduce Steps to reproduce the behavior:

1. Create a .ipynb/.R file
2. Type some R scripts such as a <- c(1, 2)
3. Start new line with a - in the .R file you’ll see variable suggestions, in .ipynb you won’t.

Setting.json

"r.rterm.windows": "C:\\Users\\myusername\\anaconda3\\Scripts\\radian.exe",
"r.rpath.windows": "C:\\Program Files\\R\\R-4.1.3\\bin\\x64\\R.exe"
"r.bracketedPaste": true,
"r.sessionWatcher": true

Screenshot

Autocompletion doesn’t see the session variables and suggestions in .ipynb:
But autocompletion works in .R:

I’m been having this issue for some time. Have there been any new developments?

Thanks for confirming it worked in older vscode versions. Looks like I need to change something in the language client or server to adapt to the latest changes in notebooks api which is broken in this case.
