I have had problems with connection and payment in transit. Maybe it’s because my balance is too low. It’s not a big deal because I stopped using Blue in 2023.

From perplexity:

Common issues users face with BlueWallet include:

• Insufficient Balance: Users often encounter problems due to not having enough balance or confirmed inputs for transactions[1].
• Balance Updates: Delays or failures in balance updates are frequent complaints[1].
• Refill Delays: Users report that refilling their wallet can take too much time[1].
• Payment in Transit: Transactions sometimes get stuck in transit[1].
• Connection Issues: Problems connecting to LND nodes and invalid LNDHub URIs are common[2].
• Fee Estimation: Incorrect fee estimation during network congestion[3].
• Dust Transactions: Transactions rejected due to being considered "dust" (too small)[4].
• Tor Support Removal: Some users are unhappy with the removal of Tor support[5].
