Tesla Delivery Date Accuracy

I ordered a Tesla Model 3 LR RWD back on March 25th, and still have not received a delivery date. On the Tesla app, I have an estimated date of 23 May- 8 June, but these approximate dates haven’t moved in a few weeks.
I’m just wondering how accurate others have found these dates, and should I expect to collect the car in the next few weeks, as it has felt like a pretty long process at this stage!
