Problem navigating forum using phone app

When I navigate a Wyze forum on my PC or Chrome app and click on a threads comments, I use the back button to return to the page with the original thread listed. However, when I do this using the Wyze app, the back arrow returns me to the forum header page and I have to re-select the forum I want to visit and start the list over again. I am using a Samsung S8 and wonder if this is a problem unique to that phone.

Have same issue on my Samsung Tab A and Galaxy 7 phone

I have same problem with iphone 10. I find the forum very frustrating because of this.
Love all the info though.
