I've had one of those lenses for my Samsung Galaxy S9 forever... but could never get mine to work! Love to see a post detailing your use of your gear.
In regards to authentication for your account... I believe that you have done everything you can, and would suggest you move on... continue your journey on the Blockchain.
I'd no longer keep tagging these individuals, as you have contacted them all, and been told several things to do... and have done said things. Continuing to TAG these individuals is not going to produce positive results in my opinion.
Continue to create positive energy and content... showing sources, gear, and apps/software used...
Hope you have a wonderful weekend!
