Please take our humble apology. You can wait for few days. Because during Black Friday the team offer another attractive discount .
You can grab that discount to upgrade your plan.

Thanks for contacting us. The team is working on some issue regarding upgrade. We will get back to you when it will be done.
Now the sale is over and the upgrade is still broken.
This is also why I now published this issue in the public forum, so everyone can see the issue.
