Similar terms are not collected

Question

Hi,

I'm trying to derive Ricci scalar in terms of derivatives of g inverse. The last three terms of the expression are similar, but they are still not collected.

For more information see the full notebooks: common.cnb Ricci_scalar.cnb (See the last line for the above referred expresssion.)

I think it's related to the bug report: sort_product bug with position=independent and identical variables Action of sort_product depends on the choice of index

Thanks.

This issue is now hopefully fixed, in version 2.3.9.3 which is the current head of the github master branch. Please let me know.
