I have the same problem.
I would suggest contacting Microsoft support through OneDrive (I did it through the online OneDrive website) and opening a support case. The more complaints they receive, the more likely the problem will get resolved.
For what it's worth, I got the following response, which is not really encouraging given how long this has been a known issue:

I apologize for the inconvenience this experience has caused and we appreciate you for reporting the issue with the OneDrive Shared folder redirecting to the web.
Please be assured that our Engineering team is aware of this problem, as it has been reported by other users, and they're actively working on a resolution for everyone.
While no action is required on your part, we may proceed to archive this case, as the fix when available, will be implemented through an update to your device.
In the meantime, we recommend using OneDrive on the web as a workaround for accessing your shared folder files. You can access your files under the shared section through:
- Visit www.onedrive.com via a browser.
- Click the shared section
- Click shared with me
We apologize for any inconvenience this may cause and appreciate your patience while we address the issue.
