Error: Unable to get network fee

When signing a transfer request in an app (currently in beta, using the nft-devnet), I get a popup saying: Error Unable to get network fee, please make sure you are connected to the XRPL node. Any idea what might be going on? I'm omitting the transfer fee from the tx record, as suggested in the docs: https://xumm.readme.io/docs/payload-transaction-data#fee-transaction-fee My transaction looks like this: const request: XummPostPayloadBodyJson = { txjson: { TransactionType: 'Payment', Destination: walletAddress Amount: `${amount * 1000000}` // 1,000,000 drops in 1 xrp }, options: { return_url: { app: returnUrl, web: returnUrl } } };

Get QR code instead of popup window with xumm.authorize().

I am using the PKCE flow for login (xumm.authorize()), but it opens up a popup window with the QR code. Is there a way to just get the QR code image that I can show on my frontend instead of opening a popup with other info? Thanks

What is the best way to send purchase transaction or NFT mint to XUMM wallet for XRPL NFT

Hi there XUMM devs, I'm new to XRPL and XUMM networks and I'm going to launch an NFT collection of 5000 arts on XRPL networks.

How to allow currency other than XRP through XUMM Wallet?

Hey there, So we have successfully integrated XUMM to create our first version of the NFT marketplace app. We only support XRP right now, but we would like to expand this to allow alternative XRPL-issued tokens like XGBL for example. But we can't seem to figure out how to do so. Let's say I have another 50 XGBL tokens in my wallet. How can I use that token instead of XRP while I buy NFT through a transaction performed by XUMM. Thanks for all the help!
