@Giiba Ah, thanks for the insight!
Since the last posts I was thinking that the reason for the difference in behaviour with getting the app back up and performing this time was actually, the app itself has had big changes in the interim period.
Ubuntu touch continues to go from strength to strength; long may it continue... and respect to you all!!
Well, uAdBlock now ok. Not quite sure of the exact steps but to cut a long story short 
deselecting the blocklists, closing the app, rebooting, opening app and selecting the lists again did the trick.
No ads on my favourite weather website!
uAdBlock app appears to behave differently with this latest update on my devices: Nexus7(flo) and BQ E4.5 on rc (2019-W41/2). Ads are being displayed on the website I use most regularly.
I have tried uninstalling the app, restart device, re-install app before opening web page. This is the sort of thing that has worked for me with previous updates, but not at the moment.
I have reverted the Nexus 7 to stable channel under OTA-10 and uAdBlock showed a pop-up on starting saying something about checking the present system. It is successful in blocking ads on the website in question.
I notice when re-installing the app on BQ E4.5 that the Blocklists are all selected as I had them before which suggests that a more thorough uninstall may be required? Might be beyond me!
Hi @aimar, My E4.5 ubuntu edition (purchased new, July 2015) is misbehaving since OTA-10 (stable) also. It crashed once so badly I thought it would never start again! Long hold of power and vol buttons worked eventually. However it seems to have a settled down a bit now. But I am considering a fresh install.
The apps I mainly use are Dekko, Messaging, Teleports and Browser. Browser is fine. Dekko mostly ok but notifications sometimes not happening until app is opened. Messaging has been weird with flickering sometimes, sent message remaining in the input box after message sent. I don't use it much but I think it has got better recently. Teleports notifications sometimes don't happen until app opened.
The wi-fi icon on the top notification bar (what's it called!) often goes blank whilst on the pull down settings the router is shown as selected and showing strong signal. Tapping it will bring the icon back.
I guess the wi-fi and notifications issues are linked. The phone has always been sluggish connecting to wi-fi and going into airplane mode. Slow also to re-connect to wi-fi after being out of range...I usually have to give it a nudge. My Nexus 7 switches almost instantly.
I wonder about the lifespan of this device and all similar devices. It might be nearing end of life. But I'll stay with it (hopefully) until something better turns up to run ubtouch on.
Ah, thanks guys; so this looks pretty normal then.
The reason for asking was a feeling that my old E4.5 might be getting a bit tired so I've been thinning out unused apps, clearing caches etc to try and make more free space in the hope it might make things easier for the phone!
Using OTA-10 stable on BQ E 4.5
The storage figure for 'used by ubuntu' in the settings has for a long time now seemed rather high. Is this normal or might there be some tidying up that can be done.
@trainailleur Ah, thanks for the upvote. Although I'm not exactly forum savvy so I'm not sure what all the upvote, downvote stuff is for!
However, the forum is a great resource for help whenever one runs into problems with UT and it reassuring knowing that there is always help at hand when one needs it.
@rdrowe You're welcome. I thought 'the purchaser' might be seen here at some point!
