Just to confirm: the TLS issue with crossword 891 was a double, hence the 2-week wait for crossword 892.
The Crossword Club gives you all the crosswords in Times newspapers, with online solving for the standard format blocked grid ones. It doesn't yet have an iPad version. iPad versions of the two papers include "onpad" solving for the 15x15 and 13x13 blocked grid puzzles.
