Have there been any unstable updates pushed to the Chrome extension wallets? Opened mine earlier today, had 3k or so DGB, opened it just now, completely empty, and no transaction history.
Anyone have any ideas? I'm pretty familiar with crypto wallets, and I haven't done anything unusual that might have deleted the wallet file or anything else, so I'm not sure what the problem could be.
EDIT: Earlier today I tried to send a tx for my balance, but it said it failed and that I needed to check my connection, however my internet connection was fine. Could this be related?
same problem , I had some dgb in my Chrome extension wallets , I do not do any transactions but now has lost even transaction history is also no

Now, Im not absolutely sure about this but I noticed DigiExplorer was going through a re-sync around the time you posted and I think possibly the chrome wallets look at this for confirmation of funds associated with the addresses held. While this was happening they may have appeared to be empty. The sync has completed now, please check your wallets and see if your funds show up now.
As someone already mentioned, a core wallet is a much better place to keep your digi and it supports the network too.
