OK, we ran a check - your post was picked up and a vote scheduled and... the vote didn't appear! sorry, happens. So, as to your original question, there are no problems using another app, so long as the post appears on the Hive chain. I have given you a manual vote from our secondary voter @maxuvd on your recent post, which will be larger than the missed vote.

If you do spot any future problems, do let me know.
