I agree, A high-tech company should have no trouble fixing such an issue. I suspect many will just go to Reddit or other venues until it's fixed. I used to enjoy XDA forums via Tapatalk. In that case, they decided to divorce from Tapatalk and created their own app., Fine, but it was never the same and impossible to navigate on a phone via the app. I'm a retired IT manager with many years of experience and I really don't see what the big problem is to create an app with a link to forums that will open to your subscribed sub-forums. No one wants to drill down through a dozen menus to get to their subscribed forums. If A/C no longer wants to use Tapatalk, they already have an app with a forum link already established. Either put pressure on Tapatalk to fix the issue quickly, or establish a working link in the app to the A/C forums. As one supervisor told me many years ago, "don't tell me what you're working on, tell me what you've accomplished."
