There are still issues with Migration from 5.5 to 5.6 that break some blueprints. Any chance we will see these fixed?

Would like to move my project forward to 5.7 and beyond, **but this is not possible if 5.5/5.6 blueprint projects are not fully forwards compatible yet.**

This has been a problem since UE 5.4, fixed in a later update for 5.4 \> 5.5.1 but Still **NOT FIXED** for 5.5 \> 5.6 (looks like the problem was found for 5.4, fixed, then re-emerged and was not addressed in 5.5).
