Does the Xcash team have any announcement on discord about syncing problem with the new mandatory upgrades of the wallets before September 31, 2018?
This is the wallet download link https://github.com/X-CASH-official/X-CASH/releases/tag/v1.2.2
Ive been using the wallet without any issues, Syncing problem is cause by your internet connection and latency. If you have slow internet connection just choose a node that is near on your country of origin for faster loading.
have you run it as admin? i have the same problem until i run it as admin and it sync perfectly smooth
