Cannot get Zwift working

Hi all,
I need help!!
I registered Zwift account in 2018 and have not been actively using it and it is still on free trial status.
I am recently wanting to get back to zwifting but could not do anything as my avatar is not moving. I tried various options as follow:

  1. un install and re install zwift apps ( i am using Hua Wei P30 pro phone)
  2. my trainer (tacx vortex 29) is connected (with green tick) on the zwift apps"
  3. i also purchased the monthly subscription and showing " subscription purchase status is pending with a note stating… member since March2018 and free trial not started.
  4. I have also contacted the support team, who has kindly help me via chat service but also ran out of idea.

I still cant get my avatar to move…

Please to hear your thoughts and solution to this.
