As the title states, prior to MessagingService’s public release I’m pretty sure that this hadn’t been the case as it seemed to only rate limit publishing.
In this case I’m publishing to a single topic with 2 other users subscribed to the same topic that are also publishing every other second on a single player server. It can be done slower however the more users that are connected to the same topic more time between requests are needed.
Effectively when publishing and subscribed to the same topic it uses twice the amount of limit requests plus incoming subscription calls even though the limitations currently state ‘publish requests’.
