This app has many of problems. When I deleted some files on my phone's google drive, it all went smoothly. But when I check the folder using google drive desktop, the file that I deleted earlier is still there. I tried to refresh many times but still the same. Then, when I open google drive on my phone, a message appears saying there is a sync problem. However, when I check my internet, everything is working fine. So, I implore the relevant team to fix the synchronization problem.
