Will that cause issues with logging in to websites with lnurl? Thank you for your help!
It unfortunately sounds like too many, yes.
In Blixt Wallet 0.6.3 (and an attempt in 0.6.2), we addressed some lnd channel pruning issues, where lnd would mark too many channels as “not suitable for payments”.
This has been causing payment issues for users as the pathfinding has less channels and nodes to work wth.
You can read more about our findings in the changelog for 0.6.2 and 0.6.3
https://github.com/hsjoberg/blixt-wallet/releases/tag/v0.6.2
https://github.com/hsjoberg/blixt-wallet/releases/tag/v0.6.3
Any installation running 0.6.3 and newer has this fix.
But if you had Blixt Wallet installed before that, you will unfortunaetly have to reinstall Blixt in order for the fix to properly work for all channels that has already been pruned.
Here’s a step-to-step guide:

So in order words, reinstalling Blixt (remember to save the seed and close channels) will make your Blixt work a lot better.
But I understand if this is a bit cumbersome.

No, LNURL authentication is done via your seed.
So if you restore with the same seed, there’s nothing to worry about.
