Are webtoon services/providers currently working and safe to use with the whole PHP situation?

I don't really know where else to ask this question, so mods I hope it is okay to post it here.

I am just wondering if services like

\* Webtoon

\* Tapas

\* Tappytoons

\* Manta

\* Lezhin

I primarily use their apps.

Are currently safe to use or working, with this whole PHP situation going on.

I don't really understand it, so I thought I'd ask as I would rather be safe then sorry.

Thank you!
