Thank you everyone (^-^) Apologies for the delayed response but I think I can access both the italki app and site without any problems now. I hope you guys can too.
Miriam - I couldn't open my calendar properly when I switched to my teacher profile :)
Joe - Haven't seen you in a while on the discussion board. Welcome back! I had the same issue, only I used my teacher profile.
James S-C - I'll take note of this the next time this happens again.
