No issues with sync. Using right now

++ for brother. Still running my mfc j470 ink jet purchased in 2013. I purchased it because of their support of Linux and Android. I’ve NEVER used official ink cartridges besides what came with it. it’s printed 6900 pages

Most of the apps I’ve used don’t have smooth scrolling or start to lag and eventually crash on me after a while. Not sync. Performance is exactly like the old app.

Google sheets for years

Maybe 3 or 4 drinks before lunch you may need to worry
