I have downloaded OLX app and presently it is in internal memory. When I try to move this app to SD card it says "Insufficient space. Can't move to SD card". Please help. I am using Huawei Honor 4X handset now.
Try to move some small apps from SD card to phone memory, then try moving any apps from phone memory to SD card, as you said Ola, or any other. I did the same when I had that issue.
