Hi all!

I'm having a hard time uploading to my zoho mail account a signature (that worked perfectly a week ago, but seems to be "broken image" now), it is in .png format and less than 3mb, i'm uploading it via:

Sign into Zoho Mail account --> click 'Settings' --> 'Personalize[Email ID]' --> 'Signature' --> enable the option 'Add customized signature in all my outgoing emails' --> 'Save' --> Upload the signature by clicking on the option 'Insert Image' (as shown in the attachment) --> 'Save'.

After that, it gets stuck with the green "uploading image" animation, and i DO HAVE internet connection. 

It also happens to all my collaborators on @dashhelpme.org domain.

Prove attached.
