The above error occurs when I trying to learn new words after learning some words from the “TPO Vocabularies - Mazdak” course. This error occurs only on the web browser and everything is ok on my phone.
What should I do?
Hi hossseein,
The course creator will need to edit all levels, add or remove a word from each level then save the course. This will update the number of words inside all levels.
Thank you very much but I think there is no way to contact with course creator about this.Is it true?
