When can we expects a full release?
Something as critical as this can't be put out as a "beta." If used in production we need these fixed and we can't push through a change for a beta release.

Will there be a fix for this as well?

Will there be a fix for 3.2.7 also? Software controller, running on Windows. Thanks :)
For Omada Controller v3 or below, the fix will be based on the latest controller v3.2.14.
If you are using the controller v3 to manage some old APs, please feel free to install the controller v3.2.14.
I've updated the solution with the Beta firmware of Controller v3, and the official firmware will be available soon.

I do not understand why v 5.0.15 has not been removed from the download, this version has bugs, this has been known from day 1, I have been in contact with tp-link support about this error and they promised a fix in November but this has not happened yet.
Look at this post,
https://community.tp-link.com/en/business/forum/topic/508242
Sorry for any trouble caused.
As I know, there are some new issues to be fixed urgently, so the new released planned in November has been delayed.
I've provided the official firmware in the solution, which has fixed the "general error" issue mentioned here.

I'm afraid that the solution is for the latest controller version.
The latest controller version has fixed some issues and optimized some features, we advise installing the latest version for use.
Kind note:
If you are using the Windows Omada Controller, you may follow this solution to install the official firmware V5.0.27 directly.
Please remember to back up the current settings whenever you upgrade the firmware for your products, just in case.
