Oculus Link Not Working

My Oculus windows app is v21.0.0 and the quest is v20.0.0, will this affect the editor debug process using the oculus link.
If yes should I downgrade my Oculus PC app to v20.0.0, to make the oculus link work? But I can't seem to find the v20.0.0 of the oculus pc app, the latest one is v21.0.0.
Any suggestions are welcome
Thanks in advance.
