When opening the composer I see this in the console. Also, maybe unrelated, the insert link button is missing.
TypeError: this.navigator.when((function(){return e.active})).onUp is not a function. (In 'this.navigator.when((function(){return e.active})).onUp((function(){return e.navigate(-1)}))', 'this.navigator.when((function(){return e.active})).onUp' is undefined)
