The app was crashing for weeks when opening CS PDF, but glad to see it finally fixed after the latest update. I can log in now and it works smoothly. Sadly, I lost all my old files in the process, which was disappointing. Still, happy the app is working again — hope future updates prevent this kind of issue.

I have been with CS Scanner for over 10 years, and I learned to trust this company based on that. This app, CSPDF, has failed and was not working for three weeks, and they lost my documents. I cannot trust this app and have lost confidence in this company. It has taken weeks to communicate with the team behind this app. Do not trust your documents to this app if they are important. High chance of loss of documents. I am hoping they do the right thing and find my documents and refund me for this
