I have many issues regarding speed and lack of access to some web pages/services but I will focus on an example that I am able to constantly reproduce on my recently purchased AX50/AX3000 router:

By using the OneDrive Mobile (Android LG G5) or Desktop (2 Lenovo Laptops Windows 10) APP versions I can't download any file (uploading works perfect) but by going wired, all works flawless.

This occurs with any setup and available firmwares:

-At First use, setting up by Tether App (including the upgrade to "1.0.8 Build 20200426 rel.65338(5553)", I detected the OneDrive download issue (and many others as I stated before but I prefer to focus on the clearest example).

-I tried all the settings you can imagine, nothing helped/no solution.

-After a Factory Restore with all default settings (NO "Quick Setup" and NO Tether App), issue continues.

-After a Downgrade to firmware "1.0.6 Build 20200121 rel.54912(5553)" and a Factory Restore with all default settings (NO "Quick Setup" and NO Tether App), issue continues.

-Then I tried to setup QoS, device prioritization, etc by using the Tether App, nothing helped/no solution.

I am trying to return this unit to the seller and revert the payment because I don't know if the official support in Argentina could solve this software bug because it seems to be a Firmware issue and I can't wait to a new version.
