I just tried it again and it worked this time (I didn't get an error message.)

But this is the message I got after sending the hive with the memo:

Please come and check at Discord support channel if you still have problems :) https://discord.gg/J6JrABJ

This is the message I am getting too.

I went to your discord and I see other people having the same issue I'm having, except I'm on Linux, instead of a mobile device.
