Only received rewards from ONE device instead from 4 devices!

I have 4 devices that are all linked to the same Uphold wallet from 5 months.
BUT this month, I only received from ONE device (4.443 Bat)!
I should have received more (promise): 2.8285 + 2.115 +2.66 BAT…the amount missing is around 7.5 BAT.
I do not understand.
I do not see where the problem is coming from. Nothing has changed compared to the previous months…
Can you help me please!
