Incorrect data usage count on Voucher authentication with traffic limit enabled
I am running a voucher-based authentication with a data limit enabled (1GB per guest) for our wireless network in our small tea shop. I decided to have data limit enabled since I do not have unlimited internet (only 1TB monthly data allowance). On average, we have approximately 20-30 users daily (20-30Gb data) but on my internet provider's router statistics it shows 40-50GB of data. It's impossible for me and my colleague to use an extra 20Gb. So I changed my router password thinking someone might have accessed our WiFi network but it did not make any difference.
Upon doing my investigation, I found out that my Omada voucher is showing incorrect data usage counts. I created a 500mb data voucher for my iPad to check the statistics. I downloaded a 139MB update for an app and here are the stats on the Omada controller:

Here's the usage of one of my users earlier today.

I hope @Fae can escalate this to R&D. Thank you!
I tried to downgrade to the previous version (OC200(UN)_v1_1.7.4 Build 20210118) but it won't let me do it. I am getting in circles.
