My first zebrina🪴 Please help me rescue her😣

So my Dad has a pretty big Zebrina alocasia which started growing another one besides. He potted her and put out to the garden.

I think the potting and the heat change shocked her because outside the weather is at least 10 celsius warmer.

I saw the leafs started to go yellow and dropping so I wanted to take care of her and bring back outside. I’ve had her for months now but I think it’s just dying.

The new leaf after awhile always starts to be yellow and die off. I’ve cut 2 off already. The ones that are seen on the photos were fine before.

I searched for pests and I don’t see them, but those marks on the 2nd pic looks like bites.
Also last picture looks like discoloration

Please help me! Do you have any tips what should I do?
