[Bug] Synchronize Watch Later between Devices

[SCBionicle]

Use Cases

There's a lot of videos that I end up wanting to watch and I find it really handy to bookmark the videos in the watch later playlist, especially since the watch later playlist automatically clears when you watch the video.

Proposal

I will switch between my desktop and phone to watch videos. Since the desktop just released into open alpha, it would be very handy to the synchronization feature synchronize the watch later list between devices.

Hey Seth, that should already be synced but the view doesn't refresh immediately. Can you try opening different tabs or closing and opening the app to see if the change was made?

I'll take another look when I get home from work, and I'll post an update.

So, it does sync somewhat. It goes back and forth with adding to the watch later list on desktop, only if I have already created a watch later list on desktop.

It does not, however, download my already existing items in my watch later list from my phone to my desktop prior to me creating a watch later list on the desktop.

This may be a bug.

It would be difficult to test if the sync will retroactively add and remove items from a playlist after the devices reconnect from being disconnected.

I've had intermittent success with "watch later" syncing. Watch later occasionally syncs, but when it stops syncing I consistently see this error when opening Grayjay on my phone(GrapheneOS, Pixel6a). Terminal log is from my desktop (Fedora 41, Plasma) and I removed the session id and public key.

Hmm? What's this?

Why am I being billed with this?

[SCBionicle]

Btw, observed behavior is that new (not existing) entries sync fine to desktop if the devices are actively connected, but do not retroactively update if the changes were when they were disconnected.

I have not paid enough attention to know for sure if the syncing works fine the other way.

You are not being billed for this but for a weird reason you got emailed for triggering the job for a labeler and we ran out of the worker minutes. Anyway, we removed it since it not that useful and we don't you getting those kind of emails. :)

Update on observed behavior: any changes made on the android version of watch later is not pushed to desktop retroactively, so when desktop syncs after reconnection to android, it readds the desktop watch later list to the android device.

This behavior does not happen on any other playlist, just watch later. I'm going to open GrayJay desktop and link to this issue because this issue is related to both apps.
