I use Tawk and have enabled for mobile devices to but i don't like the fact it is constant logging me out after some time. I have to login into the Tawkto WordPress plugin daily in order to show the chat icon.
This means your chat icon is not showing up while i do have the app on mobile to engage with visitors. I will have to try Zendesk too because of this.
Don't forget about social media, people will contact you via this too!
However this can be some kind of problem if you use a VPS or Social Rabbit for promoting and using an other IP address for logging into Instagram for an example.
I think if you promote via a different IP and logging into your social media accounts from another different IP you can be blocked.
Is there anyone who can explain more about this?
