[joshtrichards]

Did this by chance start just after you first updated to v28? If not, when did it start?

Do you have any warnings under Administration settings->Overview?

[susnux]

Which version of Safari are you using?

[punkyard]

hi
i cant find the version but iOs is 15.8.2.
and its the same for Brave too which is up to date.
and its the same with nextcloud editor. yeah

[punkyard]

yes it MIGHT have started with v28
i'm not 100% sure

overview in brave

[joshtrichards]

overview in brave

I was referring to you checking in your web browser (not on mobile) whether you have any warnings or errors. :-) Though I now see you're using AIO so that's less of a concern. Are you using Cloudflare or doing any theming/customization?

Also, can you provide the output of occ config:list system (or equivalent) and occ app:list (or equivalent), as requested in the bug report template?

[punkyard]

hi @joshtrichards
and thank you for your concern

no, i'm not using cloudflare or done any customization.
I have updated my request with the occ commands as you mentioned.
Regards

[joshtrichards]

Please disable the following apps and retest:

side_menu
unroundedcorners

i cant find the version but iOs is 15.8.2.

It's an older browser, but in theory should still work.

[susnux]

I think it is caused by this issue: nextcloud-libraries/nextcloud-vue#5589

So iOS < 16.4 will not work as Safari can not handle that regex.

[punkyard]

Hi
thank you @joshtrichards and @susnux for your messaging

after disabling the two apps mentioned neither can Brave nor the Nextcloud mobile app open and show .md files: blanck

same for the other pages in my browers: there is no content.
I'm going to have a look to the 5589 issue :)

[joshtrichards]

The updated library merged for upcoming v30 via #47401

Not sure if we can do anything about this for <30.

@susnux Is vue v8.17 something we feel comfortable adding in a backport to v29?

[susnux]

Is vue v8.17 something we feel comfortable adding in a backport to v29?

Sure non breaking release so this is possible

[joshtrichards]

Fixed in #47566 (we think).

@punkyard Let us know how things look after the next maintenance release.

[punkyard]

Hi,
here is a feed back as demanded

recent released of AiO 960 has brought a tiny evolution in the display of .MD files in safari browser of my iphone: there is a spinning wheel in the middle of the screen and I can see the title of the document.

Exactly the same behavior in Brave.

In general, I still can't access Talk Discussions, Collectives (but I can see the list of the Collectives in the left panel), Notes, Forms.
I can access Task, Deck, Agenda, Contacts, Files list, Photos, Polls, Announcement.

Which logs would be relevant to this issue?

[punkyard]

I want to add that -unfortunately- users have left our instance because of too regular issues - after nicely accepting to test our Nextcloud for about a year now.

[susnux]

In general, I still can't access Talk Discussions, Collectives (but I can see the list of the Collectives in the left panel), Notes, Forms.

This are external apps and need to be fixed separately, so please report this on the respective github page of those apps.
This should be fixed with updating nextcloud-vue to the latest version for those apps.

@susnux thanks for your advice
I will do it in a second step - i think i will focus on the text app first and see after the text app is displayed correctly
