Nested Global Macro - works for GM but not for Players

Ok - I've got a bunch of stuff going on with some APIs and I'm using macros to push a chat menu to my players. It works for me, but my players just see the text posted for the macro... am I missing some long established trick? I am at a loss, so all help appreciated! I have tried the below with and without the spaces after the macro calls - works for me either way. For players the first call needs the space, after that it fails regardless just outputting the text call of the macro. All macros are set visible to All Players, and any time I've gone back into the chat menu macros I have restored the HTML escapes... #bedemoji  ?{Would you like to take a short or a long rest?|Short Rest,!short-rest #HitDiceMenu |Long Rest,!long-rest} #HitDiceMenu /w @{selected|token_name} @{selected|character_name} you have [[@{selected|Hit_Dice}]] available - [**Use a Hit Die**](!

Not at all intuitive, but there is an option when you edit the macros at the bottom to display macros for all players and that is what is required for them to roll from them. You have to scroll to see it.

They are all set to All Players - I checked already... so something weird is going on!
