Not sure if this is the right place to post this - if not, please point me in the right direction.

At the time of writing this, it is now 43 hours since I sent 10 Dero, and the amount does still not appear on the exchange I sent it to. The blockchain explorer at https://explorer.dero.io/ says the transaction has 857 confirmations - and still counting. Does this sound right? Looking at more recent transactions, I see maximum 20 confirmations. When can I assume my transaction will be completely confirmed?

This is my first Dero transaction, and I'm quite disappointed about it.
