the like button doesn't always turn on.

Description

I don't have a MWE for this one but I've noticed (on three independent occasions) that after browsing papers with the app for a bit one cannot like papers anymore. That is, after clicking on the like button the heart will turn green for a second but will then go back to gray. The bookmark button does not seem to have this problem.

I'm happy to investigate further if needed.

Could you provide steps to reproduce?

hey laurent, could you have the browser console open and see if it says anything when this happens?

the like button has an "optimistic" timeout where the frontend assumes for 2 seconds that the 'like' has successfully gone through in the server + database so that it feels to the user that it's instant. so if it then goes grey it suggests that the server doesn't like it and it hopefully gives us a useful error in the browser console

This is on my mobile and I don't think there is a console.

I can try to reproduce from my computer. I'll let you know.

Here's the desktop output. I confirm that in this case the bookmark button still worked.

Let met know if you need anything else.

One small thing, the problem is the same with un-liking. Screenshot below.

thanks laurent, will investigate further.

tried very hard to recreate this but still unable, so not much I can do right now - I suggest we see if any of the beta testers encounter it in the next couple of days and revisit if so
