Hello xeroneit support team
At the outset, I would like to thank you for the great work and hard work you are doing,
I had some notes that I hope you can solve
First, Webform does not work in Facebook Messenger
Second, when you use a language other than English, Webform is not properly arranged
I hope that there is an option to choose the location of the buttons so that they are more arranged for other languages
And to solve the problem of not working Webform application in Messenger
I hope there is an Alignment button
Webview is working fine in Mobile Messenger too. I am not sure what problem you are facing. However if it doesn't load in messenger, try by whitelist your software site url inside pages whitliste domain again. It should solve the issue. Go to pages Settings -> Messenger Platform -> White Listed Domains , Then if already your domain is there, remove it & put it again with https & save. It should solve the issue.
I just also checked in my page , it's working fine in my android mobile. You can try here https://www.facebook.com/xeroneit/ also by putting keyword demo-webview
And other language text should be display as like you will write. May be you were trying with Arabic, Arabic actually not supported by default or RTL isn't supported.
And already there is option to set button in right/left/center .
