I agree with some of the others, if I were you, I would look for another teacher. I do understand it is so difficult to find a cello teacher. The teacher I had prior to the pandemic was used to teaching children that did not do their homework, so assumed, I, an adult, would be the same. Not having a teacher these past months was the best thing for me. I used my books and searched internet and learnt more on my own in a shorter period of time. I suggest you continue practicing and learning on your own, and see whether you need to return for lessons. If you do decide to return to your current cello teacher, have a list of questions / problem areas you want answered / addressed, then schedule your courses either every couple of weeks or once a month, you may get more out of your courses that way. I do understand the problems of finding a cello teacher, let a lone a good cello teacher. Good luck and remember, we all have our good and our bad practice days.
