There has been a bug with the Blood Knight since at least the 3.0.0 release of the app, in which switching the primary attack skill from Shadow’s Edge to Ravage and then attempting to switch back to Shadow’s Edge causes the attacks to not auto-fire by holding down the attack button, instead requiring a user to rapidly tap the button to simulate auto-attack. Switching Shadow’s Edge back out for Ravage causes the attack button to behave correctly again but only for as long as you continue to use Ravage.
The only ways to get the button to work correctly with Shadow’s Edge again is to switch out the skill from Ravage to Shadow’s Edge and then teleport to an entirely different zone or into a rift/dungeon (teleporting to another spot within the same zone does not fix the button), or to relaunch the game entirely.
This bug is problematic when changing out gear and skills in the armory (whether in person or via a familiar) or simply by changing out the skill manually, as a player would do when changing from PvE to PvP, for example.
Edit: This bug still exists as of February 16, 2025 and app version 3.2.1.
Edit: This seems to have been fixed with the Sharval Wilds update (3/20/2025 update).
