Same thing happened to me on Windows. Ondrive folders shows in dynamic link on mac though, so I was able to link there and the links were retained when opening the project back in Windows" ..but this is of course not a viable workaround for most and time-consuming. But it shows that dynamic link actually sees onedrive folders..
I am pretty sure that dynamic link to/from/and within Onedrive folders used to work in Windows earlier.
