Routeros v5.x and v6.x bugs

Hello,Qeue, pcq, were working perfect on v 4.17 while on v 5.x and 6.x is making a big mess
routes in v5.x and 6.x are awful too, adding several routes is not working, is there a fix for that?

5.x working perfectly and current version is most stable version ever(stability returned since 5.22)
From your post i can say that you just don’t have enough knowledge to configure it.
4.17 is outdated, 5.x syntax should be same in most cases, but 6.x syntax, especially queue, is completely different.
Reread wiki, make labs, be more specific in your questions.
