data not loading and front-end stops being responsive

[kapil1garg]

We had a weird issue yesterday in DTR where data for the interface was only partially loading (e.g., see Delta Lab group but not DTR group on /groups page), and any UI interactions would not save (e.g., clicking a rating shows the button being pressed on the UI, but it doesn't save and the button goes from a togged state to an un-toggled state). No errors appeared in the client-side console logs or on the server-side logs.

this might be an issue with the current version of meteor being incompatible with MongoDB Server 5.0 that is being used on Atlas (our DB hosting service). Meteor updated its driver to use MongoDB Server 5.0 in Meteor 2.6

from testing bf43cc1 in DTR today, it seems like ppl were still having issues. need to investigate and try to reproduce

after taking a look at the logs, I'm not quite sure what the issue is. one thing to try at Delta Pair this week would be to have ppl install the Meteor DevTools Chrome Extension and see if the issues pop up again. if they do, we can examine the subscriptions and minimongo instance on the client-side to see if there are any issues.

from Delta Pair this week, seems like we didn't have any issues. For now, I'm gonna merge the updates into main but leave this issue open in case we have issues still.

having trouble again with syncing changes to clients. note here how, after a pool reset, the old pairings are showing. also, some folks couldnt even see this
