I think is the same problem reported here: [https://bitbucket.org/site/master/issue/4626]
My scenario and the test: I'm following 10 projects from a Team user. 9 of them have the same token id.
I commit on one of them. All projects changed theirs token ids.
So it's impossible to follow these projects using an external feed reader.
The other 8 projects, before (2 examples): https://bitbucket.org/nexusdinet/cayennezkwebapp/rss?token=a6c701921b593d65ad3f7ce01ca7f907 https://bitbucket.org/nexusdinet/nexussiee/rss?token=a6c701921b593d65ad3f7ce01ca7f907
Opps! NO!!!, i refresh again the page an now the valid token is id for all projects: 3ef3d7beec538169a86114fa0fe1c67c
I don't know what's going on here! Hope you can track this token id!
I like this feature because allow us to follow what we change easyly. Please, take a look at this and fix it.
