Bay leaf curl

I've successfully grown bay trees in the ground for decades but I'm realising that growing in containers is different and they are more prone to pests if neglected , which I have done but I've been guilted into cherishing a neglected one.
I've extracted it from a too small pot, put it in a suitably sized container and moved it to a suitable aspect and dealt with black spot. ( ok I'd tortured it.😞)
It's budding on all stems but some emergent leaves are curled. I can't see anything inside the curls. Have the bugs been and gone? Should I pick off the leaves? Can I ignore it?
I get the odd curled leaf on the ground ones which I pick off or if they get fluffy, I hose them off but  container growing seems more intense.
Be gentle with me. This is embarrassing😳
