I don't know if this is the right place, so please move this post if it isn't.
I am very pleased with the recent evolution in Winbox but I would like to report a bug.
I still have some routers running RouterOS 4.17 and, after Winbox v3.0rc12, when I access those routers, I cannot view the PPP menu in Winbox. The functionality is there, I can still use the Terminal just not the menu. For me, this problem only happens when accessing 4.17 routers.
