We might need to compress a bit the inputs because when anything validates the send & cancel button dissappear

Same happens with 2 inputs that do not validate

And with 1 they are partially hidden

Couple of things I also saw while testing:

• When I send something with meta and tag filled, I dont see that data in the explorer https://explorer.iota.org/devnet/message/775e50253cfa431fafae7f0037ad89cfbad978b7b5b958a9549b35781ecffc94
• We tested the new deeplink format and is not working, this version is still working with the previous one, is this correct, deeplinks have not yet been updated?
