Sent transactions not getting confirmed and dissapearing after getting TXID

[simonwill1]

Hello, in my zecwallet lite newly created transactions are getting sent but not into block. I get a successfull output and TXID but on block explorer i get "Internal Server Error". In Zecwallet lite i can see the transaction and Confirmations "0". Im really worried about my funds right now. I have Orchard and Sapling balances in Zecwallet lite on multiple different wallets. Now the funds disspeared and no Income on the other wallet is visible obviously. A reinstallation of the wallet is not possible beacuse the private keys of the unified adresses are saved in wallet.dat file. I cannot export the private keys of these wallets (nothing happens). Please help me fix this. Thank you.

I did ticket here zcash/zcash#6748 and it's related to ZIP-317 because it was not implemented in Zecwallet lite
