Thanks for that link. Didn't really know what to search for when researching my problem so I missed that post. Very interesting experiments. I will try out the fan on at the beginning and a few other options like slowing down the speed a bit on the next print and report back.

Yes. After the first layer - not a couple layers.
Fan is the most important fix for this. You need fan early on. I think the default is fan at 100% at 5mm so change that to 100% at 1mm and it will come on slowly over the first 10 layers. This problem you see I have not totally overcome but here are some really interesting experiments and slow motion video that explains the problem and some solutions. It's a lot to read but worth it - the initial explanations turn out to be wrong:
