To Reproduce
Steps to reproduce the behavior:

1. Connect nextcloud account
2. Sync notes, old and new
3. Wait a week
4. Sync no longer works

Expected behavior
It would always be about to sync

Thank you for reporting this bug.

• Did you see any error message? Which one?
• Is your Nextcloud files app using any password-protection like PIN or device credentials?
• Are you able to grab a LogCat when this happens? (e. g. using LogCat-Reader

Regards

[amichuda]

In terms of pin/device credentials, what do you mean? Do you mean SSO or encryption?

[stefan-niedermann]

No, i meant if your files app is protected (go to settings in your files app and check "App-PIN" (First entry in "Details" section). What is selected there?

[amichuda]

Thank you for the clarification! No I don't have either of those checked.

Regarding "Step 3": "Wait a week":

• Did Notes or the Files app receive an upfate within this week?
• Didn't you open both apps for a week or did you normally use the apps? Please be as detailled as possible here: How often did you use the Notes and the files app within this week?
• Are you using the News or Deck app on your smartphone too?

I guess this bug is from Single-Sign-On (see https://github.com/nextcloud/Android-SingleSignOn/issues/162).

Thank you for your information

[amichuda]

Hi,

Notes or Files did not receive an update. This has been a recurring problem for a few weeks now.

I did not open the apps for a while in between sessions. I think I open them every 3 or four days.

I am using the news app and I recently had the same problem there as well, although not recently (after also doing the same procedure where I re-add my account).

So should I disable SSO and see if that changes anything?

[amichuda]

After having this happen again, I've found that sync works after opening the files app, force closing Notes and then re-opening. Is this intended behavior?

[stefan-niedermann]

So should I disable SSO and see if that changes anything?

SSO can't be disabled in the Notes app.

Is this intended behavior?

No, of course not. This is a known issue of the SSO which is tracked here: https://github.com/nextcloud/Android-SingleSignOn/issues/162

There are some ideas to retry the connection a few times, but nothing concrete yet unfortunately.

[stefan-niedermann]

Please reopen if this issue still occurs with v2.10.3.

[zingmars]

How long will it take for it to appear on f-droid?

[stefan-niedermann]

Don't know, depends on F-Droid's build servers.

I guess a few days or max. a week 🤷🏻‍♂️

[stefan-niedermann]

Yes, noticed it, unfortunately. 😓

We are taking care about it in https://github.com/stefan-niedermann/nextcloud-notes/issues/752

[smilearric]

@stefan-niedermann might be fixed since 2.10.3. Thanx!

[HiperFall]

I have the same issue, how can I fix it? I've tried reinstalling both apps.

Unfortunately i can't do anything but redirecting you to https://github.com/nextcloud/Android-SingleSignOn/issues/162

Have you disabled all battery optimizations for both apps?

[HiperFall]

Have you disabled all battery optimizations for both apps?

Yes, I tried it and it worked. Thanks!

[stefan-niedermann]

@HiperFall we are trying to hunt down this nasty bug. Since battery optimization solved this issue:

Have you disabled it for

• both apps or¹
• only for Notes
• only for the main app?

Thank you in advance :slightly_smiling_face:

¹ In this case: Would you mind to try disabling it only for one of the two apps and report us if the issue appears again? (Though it might take some time for the optimization system to react again and drop the connection)

[HiperFall]

@stefan-niedermann

It can work if I disable optimizations for the main NextCloud and not for Notes. It's important if the battery optimizatons are disabled for the main app.
