Love this App, got the premium, allows me to fulfill what I need most the time. would love if there were more templates, both page and notebooks covers, or if you could save pages as templates and make the whole page templates easier, aswell as adding cross platform compatibility and saving of the notebooks so i could have the same notebooks on my different devices.

I am Flexcil paid user. Today I purchased Oneplus Pad 3 (Tablet) - 12 GB RAM / 256 GB in India and also Oneplus stylo 2 ( Stylus). What I noticed, the dedicated buttons / gestures of Stylus pen is not working on Flexcil app for switching tools from Pen to Eraser or vice versa causing severe inconvenience while writing notes. While other apps have support of this feature of switching tool for Oneplus tabs. Kindly bring this switching features for Oneplus users by an Update. Thanking you.

When there’s a conflict between the data on my device and the cloud, I choose to merge them, but the app keeps crashing during sync. This makes it impossible for me to finish syncing and access my data at all. Moreover, when I try to open this app on another device, it just crashes every time. Please improve the sync function. * Problem fixed after updating the app
