Does anyone know if there is a restriction on the maximum string length when creating a FCM topic (for the client) to subscribe to?
For example, I need to create a (unique) FCM topic (for my FCM app account) such as "Blaine Lake (RM) Division 1".
For example:
The above topic string will be built from combining 2 strings from 2 tables:
Table 1: "Blaine Lake (RM)"
Table 2: (foreign key into) "Division 1"
I have explored Google FCM documents and cannot find any reference to string length restrictions.
Any Suggestions that may work better (such as string value converted to byte value)?
Thanks
