Hello good people :)
As we AppsScript add-on devs know, Apps Scripts which are using the Rhino engine have to be migrated to the new V8 engine until January 31, 2026. We tried this migration few years ago, but we were forced to stick with the Rhino engine due to an ongoing issue with multiple accounts.
How are we supposed to migrate to V8 if the issue prevails for several years? We cannot ask our customers (from official docs) "Open incognito mode" or "Logout from all your Google accounts". Any advice would help!
Thanks.
