Thingworx 9.1 auto-refresh function doesn´t work for contained mashups.

The Auto-refresh function in Mashups 1, 2, 3, and 4 works as expected, but once those mashups are included in the main mashup using the mashup containers the auto-refresh function configured for the main mashup doesn't update the states shown in each mashup.

I found some information related in the following links

Auto-refresh function not triggered in Mashup with Master, Contained Mashup or Mashup displayed as popup in Thingworx:

I implemented the approach suggested by @c_lowy using the legacy Auto-Refresh widget instead of the function. It works but only if the contained mashup occurs in only one level.

I made a test with this approach but to get each mashup updated in the main mashup the system is sending a lot of requests to the server.  I worried about the possible bad effects that this could imply on the performance of my application.

Looks like the solution to this issue will be published in future releases. "Fix planned for ThingWorx 9.1.3 "Corrected in ThingWorx 9.2.0".

Does anyone have the same issue?
Does exist another way to solve it?

I really appreciate your help and support.

Best regards,
