With opt-in pmIgnored: false is required on map creation to set up map.pm. This is not specified in the docs.

Lines 60 to 70 in dbf6c6c

	function initMap() {
	this.pm = undefined;
	if (L.PM.optIn) {
	if (this.options.pmIgnore === false) {
	this.pm = new L.PM.Map(this);
	}
	} else if (!this.options.pmIgnore) {
	this.pm = new L.PM.Map(this);
	}
	}

When opt in is set to true before a map is created { pmIgnored: false } is required in options. Otherwise map.pm is undefined. This is not mentioned in the docs.

I've opened a pull request that adds a line about it in the docs: #951. However i was surprised to find out that when opt in is enabled newly drawn objects cannot be edited too. Is this by design? How can i enabled opt-in and at the same time allow editing new layers?

Yes this is the expected behaviour
https://github.com/geoman-io/leaflet-geoman#opt-in

All layers will be ignored by Leaflet-Geoman, unless you specify pmIgnore: false on a layer

But you can add in your PR something like "layers will be also ignored if they are newly drawn"

Fixed with Release 2.11.3
