Teacher Class123 Customer Insights

1. Please save yourself the headache and use a backup app!It's nice for kids or teachers to teach with or play with my only problem I am not a teacher and what is and to school what the is that huhhhhThe app does not follow the formatting of the announcement when posted from the computer.. and joins all the paragraphs tgt... No bold no underline, totally zero formatting kept.

2. Collaborators (no matter which platform) can't send messages to parents.. which is quite useless since different teachers would be teaching the class and would want to contact the parents when necessaryI love it.

4. Students and I adored Class 123! Used it for the past three years.
