I totally understand the need for a thread to link to the stock on the app so it is a necessary evil of having the new threads but it is the poor way it is done. 
If you need to do it before the app launch then add a copy paste as I mentioned before which takes 2 seconds and follow up with a list when released.
The annoying thing is that it is GREAT that they are adding loads of new stocks but they instantly go and ruin the good news by not actually being on the app yet 
I am sure many do what I do and read the thread then search on the app for history etc but it isn’t there so can’t press to watch. I know it is a 1st world problem but such an easy thing to make clear and user friendly.
