I often see some symbols inside the grid and in the outside clues also. Whenever such a grid comes, I cannot solve the grid. But there are valid timings registered by others. Is this a local issue or am I missing something? Just attaching a sample from 17th April. This has happened at least 4-5 times earlier also.

Sorry Rakesh, it's my fault, an oversight.
Now everything works as it should, I hope.
Let me know if anything goes wrong.

Thanks Lenzo!

I opened the same grid (Apr 17th) from the archives and it opens fine now. Hopefully it is resolved now.
