Hi Kenshin,
Thank you for contacting the Microsoft Community.
I can see how important it is for you to ensure that your device will pass the Pearson VUE system check as you have an exam scheduled for next week and you are experiencing technical issues, allow me to provide the best option to move forward.
For immediate assistance regarding the OnVue app, please reach out to the Pearson VUE support team directly. They can see your appointments and guide you on how to resolve the issues you are experiencing. (You can expect a response within 3 to 5 business days)
Pearson VUE: Customer service :: Microsoft :: Pearson VUE.
You also have the option to take the exam at a testing center if you want a more stable test environment or use a different device that meets or exceeds the Recommended Specification stated on the OnVue Technical Requirements for the Candidate page if you want to take the test online.
Moreover, if you are an ESI learner and you have questions or concerns about the ESI discounts used, please reach out to the Enterprise Skill Initiative support team. (They will get back to you within 3 to 5 business days).
