Archer c6 poor internet through WiFI performance with MU-MIMO Enabled

As the title says, I'm experiencing incredible poor internet performance when TxBF,MU-MIMO is enabled.
I have the modem connected directly to my Archer C6, then a TL-WR841N/TL-WR841ND wired directly to it.
Both router WiFi were manually configured to operate on channel 6 at 20MHz. Both routers perform well without MU-MIMO Enabled.
To get to that conclusion, I had to do many tests, using my mobile devices and testing their speed. It seems that it hits only those.
When my desktop computer was used, I measure its speed and internet was working at 50mbps, but the same test on my iPhone 8 started at a 50mbps download speed for about 1 sec and then decreased rapidly to 1mbps, while upload speeds were constant at 6mbps, in every case.
There are currently about 10 devices connected to my home network, I'm not really sure how MU-MIMO works, but reading around recommends disabling the feature since it performs really bad.
The internet speed goes back to normal once MU-MIMO is disabled. I couldn't even load an image on Instagram, or read a blog post before that.
Am I missing something here? How is it possible that MU-MIMO, which should improve devices performance is actually decreasing it.
