Multiple issues with creating a marketing email

[JaredW748]

Hi, I am having multiple issues while I create a marketing email. Anything from uploading a new photo, lag time in typing, the "send a test email" option is no longer visible, errors note (see attachment) "Error #400, Bad Request" I start typing then all of a sudden it stops inputting what I am trying to type. I am working on a 3 yr old chromebook with high speed Verizon internet. please email me at with advice.

Hi @JaredW748. We can start with some basic troubleshooting to get an initial overview of what's happening:

• Does this happen in multiple browsers?
• Does this happen in incognito/private mode?
• Do you use extensions or add-ons?
• Can you test on multiple networks?
