Doesn't seem to be fixed in BETA3 for my reset and config entered by hand again AX86U routers (x2). Traffic analysis not working as expected, and when you move the QOS categories around under custom, another QOS category seems to be changed as the "default". I can clearly see streaming traffic not being registered - even the QOS Dials do not show the traffic flow on download and upload. Whole thing looks a mess right now - was contemplating going to stock for a bit as no previous Merlin stable for AX86U. Also gets loads of issues with custom icons showing or drop down menus suddenly dropping down and showing some of the textual options like on the DHCP reservation pages, wake on LAN page and custom schedules for wireless pages; the icons sometimes appear or not, appear too big and other times can be fine. Doesn't matter the browser whether Android phone, tablet or a computer. The JFFS was cleared at time of router reset so not corrupt info there, browsers also cleared.
Teething troubles - just hope Merlin can resolve with Asus, been using his firmware on the RT-AC86U previously for 2-3 years and all was good by the production release.
