Should be concern?

For the past few weeks I have had small quick catch’s ups with my manager who is new to the workforce as well. I had an amazing manager prior and he was always so supportive and trusted my work , which made me naturally want to do good at my job and I was. Got lots of praises for my work up until the new manager joined and now wants a one on one catch ups.

She would ignore all the implementation and the project I completed and jump right into the petty errors I have made. Mind you, she also makes mistakes that I have called her out on as well, but what kept standing out to me was how she would keep saying after pointing out the minor errors “ we will see how you go during your probation and whether you improve”

She is also on probation and had made quite some mistakes as well and I would call them out and she would either dismiss it or say “ oh I’m just new and still learning” But when I make it’s her bringing up issues and saying how she wants to see how I improve during probation?
