"We're sorry. The lab environment needed to complete the exercises in this unit is temporarily unavailable." for training "Optimize query performance in Azure SQL"

Question

Hi Microsoft Q&A. I get this error message for all 3 exercises included in the training mentioned in the title:

• https://learn.microsoft.com/en-us/training/modules/explore-query-performance-optimization/8-exercise-identify-resolve-blocking-issues
• https://learn.microsoft.com/en-us/training/modules/explore-performance-based-design/5-exercise-identify-issues-database-design
• https://learn.microsoft.com/en-us/training/modules/evaluate-performance-improvements/5-exercise-isolate-problem-areas-poor-performing-queries

Training in question: https://learn.microsoft.com/en-us/training/paths/optimize-query-performance-sql-server/

Being logged in or not has no impact. Changing browser (Firefox vs. Chrome) has no impact. I tried accessing the pages multiple times, hours apart between my first and latest attempts, but no impact.

Is there anything I can do on my end to access the lab environments, or is it out of my control and the issue is on Microsoft's side? For the latter, can I expect this issue to be resolved eventually (any specifics regarding the timeframe would be appreciated).

Similar question for a different training (which has a link to yet another similar question), but no resolution from what I can see: https://learn.microsoft.com/en-us/answers/questions/1682639/were-sorry-the-lab-environment-needed-to-complete

Thank you for your help and time in advance.
