They've became buggy these days and after visiting my account there's an error message that says, they have an issue with their wallet. Maybe, they are upgrading their system and that affected the wallet itself.
These days? I thought they were since 2017, or even earlier. I have blockchain wallet using its android app, and I can't access them ever since I encountered such problem after an update until now,
thread.
I haven't used them for a long time, oh my blockchain.com wallet for real they've been buggy for that long? they even asks for KYC now to be eligible for airdrops.
^ I used them recently but I not satisfied with their service, I dont know why they had delay transactions in confirming the block before it becomes confirmed. Probably that was what the experienced by OP. I don't think so if that is a bug or probably OP did not refresh the site and the balance did not show quickly. Nevertheless, the cloud wallet as of now is not safe, a hardware wallet is the best but you need to spend a little amount of your money. There's is free Electrum wallet, so far, this is good.
Even you refresh the site or press that refresh button they want you to press, the browser isn't loading. It's a total bug and I think they are aware of it but don't have any plans of fixing it asap. Electrum, wasabi and bitcoin core are good options but electrum is the most popular.
