SQL course give "No output" on every practice

Question

While doing SQL course I noticed that Sololearn started to give No Output message every time, even when putting simple queries like SELECT * FROM (any table name). Is anybody else experiencing the same? Even when I select previously done practice question (checked and marked as Correct) and run the same saved code, it shows the same "No output" message as the only output.
