Bert,

When making/creating a link in MobileSheets, MS asks Genos which Registration File it has loaded and which registration button was pressed. Genos’s answers are then stored by MS both as a ‘Send on Load’ batch command and as a ‘Load on Receive’ batch command. And that information is saved to the song in MobileSheets. Noting about the link is saved on Genos itself.

Now when you load that same song later in MS, MS will send that ‘send on load’ batch command to Genos, in order to ask it to load that registration file and to press that button. Which Genos will do if it finds the registration file. If it does not find the registration file, nothing will happen on Genos apart from pressing the requested button in the currently loaded registration file.

On the other hand, if you load a registration file and press a registration button on Genos, Genos will inform MS that this has happened, and MS will look in it’s database to see if it finds a match for those events among the ‘load on receive’ batch commands. If it does, MS will load that song.

That's how the link works.

As a result of the above, renaming  or moving a registration file on Genos, will break all links to that registration file. Creating it again with the same name will re-enable all links …

All of the above explain some of the things you have experienced.
There is no explanation for other things you saw happening. Because they seem not logical. Mr Spock, in the days of Star Trek, probably would have said  ‘Does not compute’ … 

Hopefully these unexplainable things were just the result of a rare combination of events and or timings and you will not encounter them again.
