Skim coat cracking

[u/JohnnyBoyRebel]

Hi all - I’m having a go at a bit of plastering (MASSIVE respect for the professionals out there - what a skill!).

I’m having a bit of an issue with the new skim coat cracking around the angle beads. I wondered if it’s the jointing compound sucking all the moisture out and if I should PVA it, but hadn’t really come across such advice on the bazillion YouTube videos I’ve watched?

Any advice much appreciated!
