Used your service for 1st few posts of mine & also doing it for comments now. Love it <3

Here is the problem tho: Last couple of days I can't upvote posts tho. No matter how much SBD I am trying to send to upvote post it shows this problem ->

refund: Sorry, we could not upvote you with 1.400 SBD ⇒ $3.85, please try a different amount. Our website https://www.minnowbooster.net has a graph with what sends are currently working.

Tried sending it at different times, different posts and different amount, the issue remains the same. You have any suggestions?

Personal Note: I thought maybe issue could be that I tried to upvote posts that were originally made in DTube/Zappl. Could that be an issue?
