I propose that Microsoft create a dedicated core group of global partners to test new features and module purchases before their official release, such as subscription billing. This group would help identify bugs and documentation gaps early, ensuring that products are fully functional and well-documented at launch.

If immediate resolution of all issues is impossible, partners should be promptly informed of known problems and recommended workarounds until fixes are deployed.

While the current three-month Sandbox preview is valuable, partners often focus only on features relevant to their immediate needs during this period. Consequently, issues may arise months later when partners begin using modules they had not previously tested. A dedicated testing group would help minimise these challenges and improve product quality and partner experience.
