### Description:
Clients do not receive push notifications about new messages. Both Android and iOS apps show the workspace version as 6.6.0, although the admin panel reports 6.6.4. When sending a message to someone, an error occurs saying `unsupported version` (see logs below), and the recipient does not receive a push notification. Sometimes restarting the docker container solves the issue for a few hours, but after that, the issue comes back again. This problem started about 1-2 months ago, most likely after upgrading to 6.6.x. Notifications worked fine before that.
### Steps to reproduce
1. Send a message to someone who has the mobile version of RocketChat installed
### Expected behavior
Recipients should get a push notification about new messages.
### Actual behavior
No push notifications are sent.

The logs are from a 6.6.1 deployment nearly a month ago, but after upgrading to 6.6.4 the issue still persists.
Is there anything I should look into to help resolve this issue?
