Send Tab feature broken

**Description of the issue: Send tab feature takes usually an hour to appear on the target device

**Steps to Reproduce (add as many as necessary):
Open any link - Use the Send to device feature - Wait a long time - the Tab usually appears.

Expected result: As it is a simple link, I would expect for recieving the tab on target device within seconds.

Reproduces how often: Every time I use this feature, from PC/tablet/smartphone, on WIFI, off WIFI

Operating System and Brave Version W10/Android10, 1.15.75 Chromium: 86.0.4240.99
