Problem with Seafile client 2.6.9 on Iphone ios11


I have a linux seafile server 6.2.2,
I looked at my files on iphone ios11 with seafile client 2.6.4, everything worked fine.
I upgraded seafile client from 2.6.4 to 2.6.9 for iphone ios11 and since then I can not open any more files (ppt, doc, docx, xls, xlsx, jpeg).
On the other hand I have an ipad with seafile client 2.6.4 that I have not upgraded and it works perfectly!
Do you have an idea for my problem? thank you in advance


Do you have this problem with a freshly install version 2.6.9? Can you uninstall the App then re-install again?


Hello yes I upgraded the application from 2.6.4 to 2.6.9 and the problem solved, I uninstalled and reinstalled the application and it works again. thank you very much


for me it was working smooth on my iPad Pro when it was running on ios 10 however as I have updated to ios 11.3 whenever now I am opening the app it only loads a blank screen on the start up and crashes after a while automatically. How do I fix it?
with regards
