Android hangs on loading. I can see my notebook on the side and make a note. But I can’t see any notes. Just the load spinner.

I already logged out and and reinstalled. Still no notes.

Hi Joe,

Thank you for reporting it.
That’s weird. I need to reproduce it in order to solve it.
Can you please tell me what kind of device you are using and its Android version?

Pixel 2 and Android 9

Hmm, as you can see your notebooks synced, I guess it’s not a sync problem.
Does it also not work if you switched a notebook from side menu?
How about search?
I need to reproduce it but can’t at the moment.

I added some debug code for the investigation. Can you please try it?

  • Version: 3.2.0
  • Version code: 37

I’m signed up and updated. Still the same issue, are there logs I can send? Also, btw I’m getting blank screen on the macOS app. Its a react error

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined.

Seems like a parent is not getting a child it expect to render… like the root component since nothing is rendering.

I’ll look into your error logs on Bugsnag.

Sorry for the inconvenience. Please try this patch and let me know if it works:

I’ve got an error log from the beta app which is:

URIError · String contained an illegal UTF-16 sequence.

This is happening while processing a particular note with encodeURIComponent to calculate MD5 digest.
I will try to reproduce it.
Do you have any idea on it? Something like you’ve wrote special characters in your notes.
Thank you for your cooperation!

I found it. It hangs when there is a ZWJ combined emoji in the title (not the body) of the note. It works fine with a regular emoji in the title.

Great to know that! I’ll research how to avoid this problem.
