Mandarin chinese errors

hi, i woke up this morning and pinyin from previously learned lessons have come back on, i am using a ipad and using the app.

additionally when i click on words, it gives a weird sigh or something unintelligible

i just tried logging into the desktop and the pinyin was not there, but for some weird reason, i could move to the next lesson, by pressing the forward arrrow.

this is really effecting my study

can anyone help with this please
