This is INFURIATING! I have used this app JUST FINE and safely for literally over a year! Why must you give me issues now? Why must you also ignore all of my app settings that tell you to stop doing this?
FUCK OFF GOOGLE AND LET ME USE WHATEVER GODDAMN APP I WANT 
If anyone knows an actually simple way that doesn't involve getting root access to my phone to bypass the ridiculous "get this app from play" garbage google has... I really could use it as nothing else suggested online works as of now.
@literalgrill@sakurajima.moe Guessing you've tried F-droid?
@JessTheUnstill@infosec.exchange I have not yet... Looks like I have something to dig into...
@JessTheUnstill@infosec.exchange Oooh okay, I don't think this will work in this case very sadly. DentalE is very much a thing made by a specific company.
@literalgrill@sakurajima.moe ah then you can probably search for "DentalE apk", download it, and install it manually (after telling the phone 15 times 'yes I know it's scary and bad and stop playing nanny bot to me'"
@literalgrill@sakurajima.moe looks like https://apkpure.com/dentale/jp.dentalx.dentale has it
@JessTheUnstill@infosec.exchange See, that's the silly bit! I've had it installed from there for quite some time. Now all of a sudden, if I try to use it in any way, it tells me I have to "get this app on Play" and won't let me use it in any capacity.
It seems to use some sort part of Google Play to function, so I can't just keep it off the whole time. But even if I disable it while downloading or turn the Play safety scan part of the software off... It just still suddenly won't let me in. Can't figure out a good workaround yet.
@literalgrill@sakurajima.moe Though it's been a long time since I've checked which are the legit apk sites and which are the malware ones.
@literalgrill@sakurajima.moe You'll have to do some research
