initial one, but what effect would any such double minimum have on
ice recovery?

There is a chart here where you can see the minimums, and by placing
your cursor on the graph get the values.

And another graph doing something vaguely similar:

Although the refreeze began quickly thsi year it has now slowed down,
and may set a record low for the day of the year in the near future.
The "cause" may be this

Arctic is failing to cool.

Saw an animated map a day or two ago, probably on Twitter, showing how
unusual warmth had been affecting the Arctic but that it is coming to
an end so the temperatures should soon drop somewhat closer to normal.
