Solution
There might be several causes to this issue:
Quota exhaustion
Check the available quota on Acronis side: Offering items and quota management.
Error in usage/quota synchronisation
Check quota on Omnivoice side.
Quota visible in Acronis not equal to quota visible in Omnivoice
Wait for 1 hour and if reproducible contact Omnivoice support.
