On the FAQ page on this forum it says:
"Q: What features are currently supported?
- Access to your Logos library*
.....*Not all resources are available on mobile devices due to license restrictions from the publishers"
Is there a list somewhere of precisely which resources are not available due to this restriction? - knowing could save me a lot a time searching in vain; my laptop version says I have 525 resources available, my smartphone version has 226, that's quite a difference!
