Canary just removed options from new tab page.
DavidGB I agree that it's a bit frustrating to have a feature then have it removed, but I guess that's the nature of the Canary channel - being the most experimental, and most fluid in terms of features & reliability. I suppose that if we want a more stable version (for reliability and feature set) there are always the other channels.
To me, Canary channel is like a science lab where different ideas and permutations are tossed around. Maybe also certain minor issues in other channels that don't effect the use of those particular features normally but are being improved in the Canary channel.
I'm a committed Canary tester, but I'd like to reiterate that from a testing perspective, it would make more sense to provide a change log (including new flag options) for the channel so we testers know specifically what we're supposed to be testing. Otherwise, there's no guarantee that we'll notice new items that need to be tested, defeating the whole object of the exercise. It also keeps it interesting for the enquiring mind! 
Any input from Microsoft please?
Update today to 84.0.506.0 and my new tab page options are back to what they were. Seems a bit .... pointless.
Yes, I know it's Canary and what that means. I have Dev installed too, and I don't actually use either to browse with other than minimal testing of certain things each update. There's absolutely no question of me moving to Edge unless and until some things I need appear in Android Edge (my requirement to sync between laptop and Android phone means both platform's versions of a browser have to be acceptable for me to consider moving - it's either both or none, and with the lack of progress in certain areas in the Android Edge that's currently 'none'). But as I said above, I think it is very counterproductive to Edge testing for there not to be somewhere where one can easily see which features are A/B testing, so in situations like mine yesterday I can know if something disappearing is A<>B switch or a bug that needs reporting.
I must say that after hunting through the edge:// pages looking for any list of remotely configured off or on features and not finding one, but seeing all the telemetry being sent in to Microsoft down to e.g. max number of tabs open at the same time, I can't help wondering how useful such telemetry really is. The figures for me, for example, only represent daily (in Canary) and weekly (in Dev) quick checks of a few things and are not remotely like they would be if Edge was actually my default browser. I wonder if they discard much of the telemetry from people like me who don't have Edge configured as default browser as otherwise we'd be skewing the analysis away from normal usage cases.
