Timeline for eVisa

Hello,

I completed all the required steps for my eVisa application on September 23rd and received an email later that day indicating that I could view my eVisa. However, it's now been 8 days, and I still cannot access my eVisa when I log in. The page displays the following message: [insert message].

Does anyone know if there's a standard timeline for when the eVisa becomes accessible?

"We cannot show proof of your status
This might be because:

your status is not ready to view in this service yet
your visa or immigration application is not yet decided

If your status is not ready to view
We will contact you by email when you can view your status online.

If you have made a new application
A decision outcome email or letter will be sent to you.

If you are usually contacted by email, remember to check your email spam and junk folders.

If you need further help
For further help, contact UK Visas and Immigration."

eVisa system is not yet fully functional. Errors are reported regularly. These may be rectified soon. I suggest contacting UKVI or complain
