encrypted TW on mobile chrome browser shows inital tiddlers

[jeroen ophetweb]

Hello,

I just started using TW. I use a desktop version where I keep all my (mostly work-related) notes, but also contact information. I use it with FireFox so I could use the save plugin. Every once in a while I send a copy to my Google Drive folder and then download that to my phone so I have my TW offline available on my phone (mostly for contacts in my TW but also to look up information, practically no editing on the phone). 

This works fine. My TW is encrypted but when I open the TW with mobile chrome it gives me the decrypt dialog but also shows the default tiddlers. No top secret information there but it is a different experience that on the desktop. Without decrypting the links to other tiddlers from the default tiddlers are not working so that is good. 

I guess this caused by the mobile chrome browser I am using (using android 7.0 on Moto G4) but I wonder if anybody has experienced this before and has any clue about how to fix this. 

Regards,

JeRoen

Although I haven't experienced this particular problem, I have noticed that many times when I load a TW page with multiple input fields, it will show me a mix of both old and new inputs. I have to reload the TW page to get rid of the old inputs. This happens like clockwork on my mobile devices using Firefox. It seems that the browser is keeping bits of the last version of the page in its memory.  I suspect that the same thing happens with the encrypted page. Perhaps you could try reloading the encrypted TW file in your browser and see if that clears the old (unencrypted) default tiddlers.

Hello,

A refresh of the page does not change anything. Tried it with FF even but the same. Also in incognito windows it still shows the default tiddlers. No problem for me personally. Just to follow-up.

Hi Jeroen

This is a very peculiar problem, and I’d very much like to see it tracked down. The possibility of a weakness in our encryption mechanism will always be wrorying.

Mark’s comments make it sound like the issue some kind of caching performed by the browser. It would be interesting if you were able to try another browser on the Moto for comparison. If the browser provides a means to empty its caches you may be able to use that to track things down too.

Best wishes

Jeremy

Hello,

Sorry for my late response. I had some time today and I installed the following browsers on my Moto G4 phone all of which show exactly the same behaviour I mentioned in my first post. I tried with:

FireFox

Opera

Opera Touch

Chrome

Brave browser

All of those with the most recent version available today (June 23rd). 

As I mentioned I mainly use my TW on the desktop and only once in a while (weekly) copy the most up-to-date version from my desktop to a cloud storage (for now Google Drive). I then download the TW file to my phone (so I do not run it from Google Drive) and in my downloads I use the "open with" option and after choosing the browser I work with the TW file (mostly read-only). Alle the above mentioned browsers show the default tiddlers beneath the green password screen and you can read and scroll them. 

Links to internal tiddlers do not work, but links outside the TW file work without entering a password. 

It where all fresh installs or I deleted all private content so there should be no chaching error. On all those browsers a reload after the initial page-load did not change anything. 

Regards,

JeRoen
