Cannot change sim card online. Support reports feature is removed until further notice

[Upcraft]

For last few days I was trying to change a sim card through self service like I have done many times before.  It always came up blank.  I thought the problem was temporary and I did not need it done immediately so I tried again later.  After it still wouldn't work today I contacted telus support through twitter private message.  They reported to me that the ability to use change device to switch sim cards is removed from the system until further notice.  Here is the screenshots of this:

I had the same issue. I changed my SIM card recently and it was pain free. I called in, gave them the number and they activated it. Only took a couple minutes.

They notified me that it now displays a message on the screen saying "We're
currently making system upgrades. Please contact us for assistance."

That's the same error message I encountered before I called in, as it suggests.
