OnePlus 5T: Cannot draw with partner

[patrick-ucr]

Hi,

I am using two oneplus 5T with ARCore installed and I cannot see the two-people logo at the right-bottom part of the screen to start draw with a partner. Checked app permission and bluetooth was enabled.

I tried the exact version 2.1.4 and it worked on my other Pixel 2 phones.

Please advice what may cause this issue.
