On August 11th I posted "Parallels 17 Tools limits display to 1024x768". Sadly, this issue re-appeared in 17.0.1 right after Tools auto-updated in macOS Big Sur. My display is stuck at 1024x768 and will not resize. This time Ubuntu Happy Hippo worked fine after the Tools update. I've uninstalled and reinstalled Tools a few times, both automatically and manually, nothing works. I sent technical data: 378777882.
