Had a quick search: “Grow Alocasia ‘Polly’ in bright light out of direct sunlight, in free draining peat-free compost. A minimum temperature of 16ºC is perfect, ideally in a humid location, such as a bathroom. If the room isn’t humid enough, you can increase humidity levels by standing the pot on a tray filled with pebbles and then add water until it rises to just below the bottom of the pot.”
If relevant, try addressing humidity and ensure it stays out of direct sunlight. It could be waiting until conditions are favourable.
