cannot install apps on Apple Watch SE
I've factory reset my iPhone 11 and paired it to my Apple Watch SE. Both iPhone and Apple Watch SE are now in their latest software version. After the sync and setup are done, iPhone attempts to install the apps on Apple Watch SE. I can see, one by one, app appears on Apple Watch, and asks me to Double-Click to Install. After double-clicking the side button, the word 'Processing...' appears and a sound can be heard. However, none of the app is installed.
I've restarted both iPhone and Apple Watch and try again. Didn't work.
I'm pretty sure the wifi and bluetooth are working. I can also receive notifications from the native Apple apps that come in with the Watch SE installation.
Any suggestion to fix the problem is appreciated.
Thanks
Apple Watch SE
