Information on passports for trans folks is moving fast right now with a lot of things unconfirmed or in a confusing state.
TL;DR it seems like new gender marker changes and ones that were in progress are already frozen. There is an unconfirmed report of someone’s document’s being confiscated but this seems like a one-off. Doesn’t mean it can’t happen again but doesn’t appear to be a policy of any kind. Be careful and stay safe
