do you use 2.6.0 with a new created Meeting SDK (without SDK credentials?)

- SDK Key is **36 char** long (apps created before Feb 11, 2023)
- Client ID is 20 char long

if yes - this is not possible, you have to upgrade to 2.10.1 or newer

you have a mixed installation 2.6.0 with libraries 2.10.1 → result: error 403 forbidden
