OP, without COVID19 you most likely would not get much communication immediately thereafter. We got the ‘congratulations, so excited to have you’ when we accepted early April.
And nothing again until late May. (Placement tests).
And then mid-June (results of placement tests and elective/schedule requests).
And then late June (health forms/insurance/emergency guardian assignment forms).
Mid-July (preseason athletics invitation) quickly followed by new student move-in/orientation schedules
Mid-August (confirmation health packet complete, contact and travel method approvals, waivers, etc)
Late August (preseason schedule from coach). -I actually think we were driving across the country with DSs belongings when we got this one.
As @CTMom21 and many threads have indicated, many families have not committed yet and many will wait until A10 to do so. So to get much information before that date even without a pandemic is generally unheard of.
