Secret Wars aged everybody by eight months due to a timeskip before the All-New All-Different linewide relaunch - Squirrel Girl for example was now a second year student instead of a first year - and both Ms. Marvel and Miles Morales have subsequently had a new school year start (meaning that Kamala, who was 16 in 2014, must be 17 by now - Miles is the same age). Anya can't still be 16 if they're being consistent even among the spider books, let alone linewide.

Franklin has finally caught up with his missing aging, by the way, he's now in his mid teens, as someone born in comics published in the 1960s should be by now.
