I have a Samsung Galaxy S8 Plus, with Android 9.0, and Flowx 3.346. After a long period of not using Flowx widgets, I tried to install one, but it won’t. I go to my list of widgets, then drag the Flowx widget to where I want it, but the Configure Widget screen never comes up. Instead, a blank screen comes up, and I eventually get an error message telling me that Flowx isn’t responding. I have cleared Flowx’s cache and data, then uninstalled Flowx, restarted my phone, and reinstalled Flowx, but I still get the same error message, that Flowx isn’t responding. I also have Flowx installed on my Samsung Tab S5e, with Android 11.0, and Flowx 3.346, and get the same results, when I try to install a Flowx widget. Doesn’t matter if I use the stock launcher or Nova. Having no problems installing widgets of other apps.
