Hey guys, I just updated the Sendbird desk framework for iOS to v1.0.16 and all calls are now returning the following error: `[desk401100] Authentication credentials were not provided.` I haven’t done any change in the authentication flow since I started using it (more than a year ago) and haven’t seen anything new on the readme steps. I rolled-back to the v1.0.14 and everything works with that version or any older one. Any ideas of how to fix this or is it a bug into the framework? Regards, Oscar ---

Hey @odm, Could you share with me (my DM if you prefer), your login flow? Just so we can compare what it looks like? I’ll take a look at any changes that could affect it. ---
