I have received my new batch of ESP S3's and tested the blinly sketch to confirm they operate.
I loaded a time sketch and the boards go into a continuous state of rebooting.
In the old ESP you could see debug information, but the the new S3 USB port does not reestablish its connectivity to the PC.
This prevents any diagnostic information from being visible. Also the board will not accept new code downloads.
I was able to use the two button press boot loader technique to regain control, but there is still no way of getting any prints during the "start" phase in Arduino.
2 questions:
Is there a way to see print information in Arduino during boot up?
Is there JTAG support for the Adafruit ESP S3 feather? - this would be preferred anyway...

Re: Debuging the S3 in arduino
Try using the hardware debug TX pin:

I don't think there are any JTAG connections, but I'll double-check that.

Re: Debuging the S3 in arduino
UPDATE: The S3 has a built-in USB endpoint for JTAG control, so you don't need a traditional JTAG pod:
