IRCC is giving refusals in bulk this month. I think if they wanted to reject you, they would have already done so , I think delay is positive because they will gives approval in bulk as soon as they are completely ready to welcome studentsEven if it was true, we should have heard about March applicants getting approval too, but I haven't anything of sorts. All the recent approvals are from late applicants, which is totally absurd.
Stay positive and good luck
