Watch won't download & install apps.

[Can Inelli]

Hi everyone,

A few days ago I've bought Watch S5 44mm GPS. I'm having trouble installing apps. Please see the screenshots. Apps won't download and install.

I've tried the following;

-Soft resetting both the Watch and my iPhone.
-Updated both the iPhone and the Watch to their latest version.
-All Apps on iPhone are updated.
-Connected to various WiFi Networks.
-Left both devices charging overnight.

No Luck.

Anyone having the same problem ?
