Couple of issues that make this one a pass unless someone from Banner/Answerly comes through with some answers.
1) All of the links to the Banner documentation are dead.
2) Email to support at Hi@answerly.com bounced back stating their mailbox was full. How many emails do you have to have in there to get that error?!?
[ LMTP error after RCPT TO:<hi@answerly.io>: 552 5.2.2 <hi@answerly.io> Quota exceeded (mailbox for user is full) ]
3) Tried to embed a banner on my website using their "Instant Embed" but the banner was never displayed (Gutenberg-based Wordpress website with Blocksy). Embed code was added using a Gutenberg block. I have a second site that is based on Elementor; another Sumoling reported having issues getting the banner to display on an Elementor-based site so I haven't tried it on mine yet.
4) Misleading/Confusing messaging - "Fatos_Answerly" says the banners can be used on unlimited sites, but when you register the LTD code it says it's good for only one site. But you can "connect' multiple websites to get the "Instant Embed" code for a banner. So really not sure if one LTD code lets you add banners to multiple sites or not.
5) I had the understanding that one of the uses of Banner was to collect email addresses for email lists, there are even integrations to a number of popular email marketing platforms, but it's not clear how to add a text entry field to the banner. So far it looks like just plain text, emojis, and links can be in the banner.

Happy to update my review/rating if these are addressed satisfactorily, but as of right now you'd be better off lighting your money on fire - at least that way you get a little heat and can maybe roast a marshmallow or two.
