Migraciones is currently more dysfunctional than usual. Hard to believe, but yes.
I use a local attorney who is equally bewildered. As of Saturday, when my precaria expired, my status is that of being in the country illegally. Yet, she cannot renew the precaria online via Radex and told me not to worry about it. My documents are all clean, buttoned up and in good order. It's their problem, not mine.
A friend of a friend of a friend works at Migraciones and, with my expired DNI, will try, in my case, to determine the delay. If I learn anything of value I'll share it.
