I have an error message that prevents me from completeting SOLOLEARN's Web Development training.

Question

I am enrolled (Sololearn Pro) in the Web Development course. I am in the 'Operators and Strings' Module, Lesson titled 'Arithmetic Operators', At the end of this lesson, after 'Lesson Takeaways', I clicked on the 'Practice' HTML label and received the following message: 'Error. Sorry! it seems something went wrong on our end!'. I went back and re-did the 'Arithmetic Operators' lesson (5 times) in an attempt to clear the error message with no success. This error message is preventing me from moving forward in this course.
Please resolve this error message so I can complete the Web Development course.

It is an annoying bug in recent days.
It happens only if using a web browser.
Try the mobile app and continue.
