For a more formal tone, consider using phrases such as "encountered an issue" or "faced a difficulty", which convey a similar meaning with a slightly elevated vocabulary.
What's a more casual way to say "came across a problem"?
In informal contexts, you might say you "ran into a snag" or "hit a bump in the road", which are more colloquial ways of expressing that you encountered an issue.
Is it correct to say "came across to a problem" instead of "came across a problem"?
