It's as Michael says - we need more details. For example, I'm not sure whether the first issue in your list even covered by the Community support, as there is no proofs that the flow even reaches Gluu Server. It may be a configuration issue on SP's side, and we don't usually offer support for 3rd-party software.
In addition to what have been already suggested, I would also ask you to export both your failing flows in HAR files and share with us. Then we'll be able to see what happens. You can use steps listed [here](https://www.inflectra.com/support/knowledgebase/kb254.aspx) - please use Firefox for that task, Chrome's HARs are flawed. Also don't forget to set "Persist log" and "Disable cache" checkboxes in the console to save everything, not just the recently loaded page.
Also, please include metadata you used to create TRs for both of those SPs.
