WhatsApp floating text bar

Hello!

That at would probably be more on WhatsApp‘s side of issues, not iOS. You may have to contact WhatsApp Suppot as it would be their problem. Here is their contact information: Contact WhatsApp

I hope this helps you out, and if you ave any questions, make sure to let me know!

Have a great day!

Try to make a video call to someone from your whatsapp and check if that solves your problem.

Hi,

There's no problem with your whatsapp and ios 11.0.3 update. It might just be a random behaviour, try checking if an update is available in the app store and get your app updated.
