Hi Carlos Quintero,
We want to assure you that our team is fully aware of the issue and is actively working towards a solution. We understand that this might be causing some inconvenience, and we’re committed to resolving it as quickly as possible.
In the meantime, we recommend that you continue progressing through the Learning Paths, but without completing the exercise modules for now. These exercises are temporarily unavailable, but the rest of the Learning Path content should still help you move forward in your learning.
Once we have a fix or further information, we’ll update you right away.
We greatly appreciate your patience and understanding during this time, and we’re working hard to provide a smooth learning experience for you.
