I linked Uphold and the BAT credited to me is lesser

Briefly describe your issue:
I had around ~12 BAT in my wallet and I decided to link it to an Uphold account since I was going to change my PC. I only received 0.25 BAT though. I read through the forum and saw it takes time to reflect for some people but now it’s been ~ 3 weeks.
