Oh I'm so it's all so confusing and frustrating. Try not to think too much about it, there are so so many things which disturb sleep that many times we don't fully know what the exact thing was or which combination. Learning to roll and pulling into a crawl position is a huge developmental leap and IME developments always lead to sleep disturbance, it's just something that happens when LO are growing and we can't stop it all we can do is help them the best we can, not worry too much about AP/props and roll with it until they come out the other side. You are not alone in going through this tricky phase I promise you, we all have these tricky phases xx
I would hold on those A times one more day then possibly increase the second A to 3hrs. Some people do find the need to cap a nap, I know it seems unthinkable to try so hard for weeks to make baby sleep and then the wake him up! Others find it more suitable to let the night go a little later/shorter. I would continue as you are for now.

Those early evening night wakes, if nothing helps them it is a case of accepting this is how he is. For lots there is a solution by resolving the day time routine, having the right length nap and the right length A time before bed etc...but I know for sure with mine he settled on a good routine, was sleeping well, good mood and all that and yet still had noisy early evening NWs basically every night. He still frequently makes noise in the early part of the night and is almost 5yo but these days it is no way as hard as when he had them as a baby, he dreams a lot in that part of the night and processes all his day time experiences and developments, it just disturbs him and no amount of routine tweaking makes any difference.
Have a good day x
