I tried to open OXT and search an address, but it doesn't work (Address / tx isn't loading, tried for several browsers. I'll try tomorrow again)
Maybe someone else also can't load it 
)
Just finished testing it and had no issue when it comes to looking for an address with different formats
[BASE58 (P2PKH), BASE58 (P2SH), and BECH32 (P2WPKH)] but got inconsistent results while using it for transactions
[sometimes it loads, sometimes it doesn't] and lastly, I always get the following error while searching for a block:
NOTHING FOUND FOR THIS BLOCK. PLEASE TRY LATER.
