The good news is that this is being worked on, with software being updated both in GSAS-II and Bilbao, so there is some hope that this will be fixed pretty soon.

Hello,
I am a new user to GSAS-II (and a very "old" user of GSAS/EXPGUI).
I plan to use it mostly for magnetic structure refinement.
I have 2 issues:
1. The request for magnetic symmetry from Bilbao Crystallographic center doesn't work. I understand that this issue is in the process of being solved.
2. When I add a magnetic phase "by hand" the indexing part doesn't work.I go to the "Unit Cells List", check the "magnetic?" box and play with the "red"/"black" options of the desired magnetic phase diagram. I do that for the LaMnO3 simple magnetic structure analysis example given in GSAS-II site. However, nothing changes. No additional indexing appears in the plot window. When I change the crystallographic (not magnetic) space group, the indexing do change accordingly.

I am using version 5833/v5.7.4

Thank you,
El'ad
