Need your help about RocketChat file upload and notification push

Hi,

I deployed a rocketchat server Last week, it is great.I really need your help about two problems:
1.I can’t upload files bigger than 1M, even though in the file size configuration is 104857600 bytes, I try to change this value to -1, but still doesn’t work.

2.APP can’t receive any notification from my rocketchat server, I try to send me a test notification, but a error appears: “there are no tokens for this user”. How can I get the tokens?


thank you very much.
