no issue for me for the past few days.. however I only open 1 or 2 channels (cbeebies or nick jr for the kids) and didn't really flip through the channels

connected via ethernet, unifi 800, device NSTV2017

This month 4 of my unifi tv ids have finally been migrated. Discovered it by accident when I tried to login to the new app using 1 of these ids. These ids are from unifi accounts with the old non android STBs.

Surprisingly, when I spoke to TM hotline regarding this (I called to report about another issue but I just asked), I was told that mine is next in line but have yet to be migrated. Was also told that they normally do it on Fridays, some sort of system automation thingy.
I didn't even get the notification in the mobile playtv app.. saw someone posting about it, a msg along the lines of 'congratulations your id has been migrated' appearing in the app.
