Practice tiles after playing 4 years

I have been an eyewire player since 2012 or 2013, almost from the very beginning. While it has been a while since I last logged on I remember how to play
Why am I having to start with the practice tiles?

you are probably landed in a lv2 cell and have to do level 2 tutorials (unless you’ve completed that as well in which case no idea.)

if you don’t want to do them (now). Press escape and go to any artifact cell.
