I am registered in an Italian class. But, when I check my Canvas dashboard I am not seeing the class as published. I know the teacher published the course because the rest of the class has been able to complete assignments and access materials and I have approached my instructor about this. My instructor sent me a manual invitation and when I accept I am able to access the course for a short time span (sometimes a few days, other times just a few hours) before I find the course listed as unpublished again which results in my not being able to access anything pertaining to the class. This has happened 3 times. What are possible solutions I may explore to fix this?
