"Hopefully, if you have time."

Translation: Gobeithio, os bydd amser gyda chi.

Is "os mae gen ti amser" not possible, does it have to be bydd?

[rmcode]

Os mae gen ti amser is fine here

[Pablitisimo]

Previous sentences had fydd... after os; this one has bydd. what's the rule?

[rmcode]

There is no mutation after 'Os' so "os bydd" is the only correct version, if you see a different one please report it and we'll edit the sentence. Thanks for bringing this up.

[mizinamo]

Just to clarify - if the sentence is negative, mutation would be appropriate, right?

Os fydd gen ti ddim amser, for example, for "if you will not have time"?

[rmcode]

Yes, that's correct

[mizinamo]

I wish the corrections were a bit smarter!

I typed Gobeithio, os fydd gynnoch chi amser and was corrected to os MAE gynnoch chi amser, rather than os BYDD.

I realise there's likely nothing the course maintainers can do about this though.
