I had this problem and the following is what worked for me.
Go to the material for your tree. Open the parent material for each material until you reach the end of the chain ( no more parents left)(your master material). Plugged into your world position offset should be something to simulate wind. For me it was a material function. Either in your code or a material function you want to locate the “TransformPosition” node. Under the “Source” drop down menu, change it to be “Instance and Particle Space”. You need to do this for each material (with a different parent) that uses the world position offset to simulate wind.
I hope this helps.
