Hi @Mathieu_Ruille1!
Apologies for this setback! I'm a member of Airtable's Support Team and I was able to get some insights into the scenario you are experiencing, this is indeed a new behavior our customers should experience going forward with the Share View feature.
The actual change in URL creation is the addition of the "appId" value, as you accurately described as the "appXXXXXX" formatted value, which relates to the Base that created this Shared View link.
This should not impact the functionality of previously-created Shared View links, what you were particularly experiencing was a special instance where the old link with no appId would not redirect to the new URL structure, as it automatically should, I'm happy to confirm that our team was able to correct this for the URL you initially shared and the functionality has been restored!
There are still some URLs that do not follow the new appId structure and unfortunately are not automatically redirecting to the new URL link including the appId value, our team has identified the root cause for this and we are working on a fix, which should be reflected in-product within 1-2 weeks!
Please, let me know if you have any questions here, we appreciate your patience and help describing this!
Regards,
German H.
