Noesis not loading on start... and/or Noesis buttons not working

Anyone else having issues with noesis HUDs not loading for players in live worlds (works only sometimes), or noesis buttons losing the ability to be clicked? (data context is being updated correctly, button becomes frozen).

Very inconsistent.... somedays noesis HUDs appear everytime starting the world and the next day noesis HUDs do not appear.

Sometimes noesis buttons in the world do not work at all, sometimes they work once, but if you unfocus the noesis go out and focus back in the noesis button does not work on  the second try.

Anybody got similar issues like this or have any ideas on what to check... on player focus problems, async, etc... 

Thanks, crew!
