Hi, thanks for your feedback. We've now released an update to fix this issue on iOS 12.
Great Product but needs to be fixed!
I have been using Claro PDF for several years to read through documents and texts. It is a great tool to help in your studies since you can listen and read at the same time. A major annoyance in the latest version is a big color circle that pops up on every page and will not allow you to start at any sentence on the page. I have gone through all the settings, but their seems to be no way to fix it. It is very nice to be able to pause and start from wherever you want on the screen. With this glitch, you have to start at the top of the screen every time you stop reading or pause. Please fix this glitch!
