Problems with syncing after changing affiliate

Hi! I recently bought a new Kobo Aura and changed the affiliate so as to use the Pocket integration. However, I'm experiencing problems with my Kobo Aura after I changed the affiliate to "KoboIndigo". After I changed the affiliate, the Pocket integration did appear but then when I add in books I got outside of Kobo, they doesn't appear in the ereader and I also keep having problems with syncing. To try to solve this problem, I tried signing out of my Kobo account in the ereader and sign in again. Using this method, the books I added in will appear, but the Pocket integration disappears again.

Does anyone have the same problem? Are there any ways to rectify this problem? Thanks!
