I haven't used monerujo, but as it says "Node must be set", that means that you need to add an active node on your wallet for it to sync. I searched about it and saw this medium post, it was from 2018 but I think would still be helpful to you (just need to read the whole content) →
What are Monero nodes and how they work in MonerujoIf you can't fix it yourself and need further assistance, you can contact
help@monerujo.ioThank you so much, it/you really helped me a lot. I already fixed the problem. I got a node here (provided by that medium post):
https://moneroworld.com/#nodes , I chose the first one on the list and it worked.
Sorry pal the first time i tried using monerujo wallet it was so complicated for me and i end up uninstall the app, i was so desperately looking for a better xmr mobile wallet until i give up but now the solution is coinomi, after several months of waiting they now end up including xmr in their wallet and it works very well
You're right pal, its complicated if you don't have an idea how to do it. I didn't uninstall it cause I'm expecting to receive XMR on my wallet. Well, coinomi sounds familiar to me but I didn't tried it yet.
Maybe you should update the wallet to latest version and wait for a while to wallet get synced with the updated node.I am also not having experience with wallet but from my experience with other wallet node errors happen when the wallet is outdated.
And also you sure that you download that wallet from official site?
I'm using the updated/latest version of mobile wallet (July 14, 2019) and yes I downloaded this on official store (also available on Play Store). I got it synchronize now with a node. I just add it manually.
If i can remember very well monerujo app uses recovery seed right? so just find another monero wallet and import the recovery seed into the new wallet, the incoming coins will appear, the monerujo wallet is not easy to use at all and its buggy and confusing as well
I don't use recovery seed cause this is my first and only XMR wallet. I am not importing Monero, I just want to know if the sender is saying the truth.
Anyway, thanks to you all for helping me out. I found out that he still lying up to now. I don't see any XMR in my wallet.
