But don't feel to upset as they have now launched there PWA (Progressive Web App). This is a link that can be added to your smart device and you computer which is the forum logo the link on your desktop. The App is supposed to load faster and so far it proves true as well as now on my smartphone
I can post pictures and videos right from my phone even easier than the Topic'It app.
If you have not downloaded it you should give it a try. I will be reaching out to forumotion and checking to we can find the new free downloadable PWA App So again sorry about the loss of Topic'It app but the came up with something even better.
