Hello,
When attempting to open documents within my connected cloud on my Pixel 7 Pro running GrapheneOS, I am met with an error. The Connection Lost error leaves me unable to see any text, whereas through my browser I can still open the documents fine.
Any help is appreciated, thank you.

hi @Thulian 
I see that you are using a Pixel 7 phone with GrapheneOS OS.
Unfortunately, I may not be able to assist you in resolving this issue as our team has not tested the application on this OS.
GrapheneOS is a privacy and security-focused mobile OS.
I assume that the limitations for the application are likely imposed at the operating system level.
Can I ask you to record a video demonstrating how the error occurs?
Thanks for responding. I was able to get it working after an uninstall and reinstall funny enough. New updates may have helped as well.
If issues persist, I will first try restrictions Graphene OS restrictions and security settings.
Thanks for developing this awesome project!
I get the error on Xiaomi Remi Note 8 Pro:

I tried reinstalling as well as cleanig all data (not just cache). Fresh install did not help.
Hey @Mtonki, 
To help us dig into this, could you share a bit more about how the issue occurs?
For example, what steps are you taking when the error pops up (e.g., opening a specific document, connecting to a cloud, etc.)? If possible, a short video or screenshots showing the problem would be super helpful for us to reproduce it.
Also, are you using ONLYOFFICE DocSpace? If so, could you clarify whether it’s the cloud version or a self-hosted installation on your own server?
Please ping @Nikolas in your reply so I don’t miss it — with lots of posts coming in, it’s easy to lose track! 
Dear @Mtonki and @Thulian
It seems we have been able to reproduce the issue, but we need your confirmation on the scenario. Are you using DocSpace Cloud in this case, and does it only affect specific large files? Is the issue reproducible when you open the file locally from your device?
Thank you for the provided data! We are going to release a fix in the next update (v.9.1).
Is there a rough release date for 9.1?
Unfortunately can’t use the mobile app at all until this fix is pushed through.
We’re planning to release v.9.1 in October.
